JML Release candidate 5.6_rc3 available

2008-12-04T11:32:40Z

Hi,

We've just made release candidate 5.5_rc6 of the JML tools. This release is
available from from the sourceforge project page for JML
http://sourceforge.net/projects/jmlspecs
or directly from sourceforge.net
http://sourceforge.net/project/showfiles.php?group_id=65346
in the file JML.5.6_rc3.tar.gz. This is a gzipped tar file.

Some highlights of the release are summarized below. See the NEWS.txt
file in the release for other changes, including changes inherited
from the previous release of JML (more or less) and many bug fixes.
Highlights include:

- Model programs and refining statements are now parsed, type
checked, and matching is enforced, using the design of the
Shaner, Leavens, and Naumann OOPSLA 2007 paper. This version
does not yet support runtime assertion checking. Thanks to
Steve Shaner.

- Addition of jmle, which is a tool for executing JML
specifications. This can be used to validate specifications,
to debug them, and to allow specifications to serve as
prototypes. The jmle tool generates Java code, so it can be
used as with any other Java code, in particular with JUnit unit
testing. For more information see the README.txt file in the
org/jmlspecs/jmlexec directory or the paper
by Krause and Wahls "jmle: A Tool for Executing JML
Specifications via Constraint Programming" at
http://users.dickinson.edu/~wahlst/papers/tool.pdf
Thanks to Tim Wahls.

See the NEWS.txt file in the release for more details, bug
fixes, and incompatabilities with the previous release.

Please let us know your comments on JML, and if you find bugs.
You can now file bug reports from the sourceforge.net project page for
the jmlspecs project,
http://sourceforge.net/projects/jmlspecs
and you can see the bugs we know about there.

JML Release 5.5 now available

2008-01-09T20:39:50Z

Hi,

We've finally made the 5.5 release of the JML tools. This release is
available from from the sourceforge project page for JML
http://sourceforge.net/projects/jmlspecs
or directly from sourceforge.net
http://sourceforge.net/project/showfiles.php?group_id=65346
in the file JML.5.5.tar.gz. This is a gzipped tar file.

Some highlights of the release are summarized below. See the NEWS.txt
file in the release for other changes, including changes inherited
from the previous release of JML (more or less) and many bug fixes.
Highlights include:

- Various changes enable the new assertion semantics. This
semantics requires that users write "protective" specifications,
in that the runtime checker will no longer attempt to mask
exceptions that occur during assertion evaluation, but will
instead propagate those out to the calling program.
Thus an assertion holds if and only if the assertion expression
evaluates successfully (no exceptions are raised) and it is true.
This new semantics has been turned on by default (to recover to
old semantics use jmlc command line option -O). This fixes bug
#1745623. Thanks to Patrice Chalin and Fredrick Rioux.

- Added the "refining" statement discussed in the jmlspecs-interest
mailing list and a new keyword "extract" from the paper by
Shaner, Leavens and Naumann (to appear in OOPSLA 2007). This
updated the checker and documents. Thanks to Steve Shaner.

See the NEWS.txt file in the release for more details, bug
fixes, and incompatabilities with the previous release.

Common JML Tools release 5.4 available

2007-02-08T15:26:44Z

Hi,

We've finally made the 5.4 release of the Common JML tools. This release is
available from from the sourceforge project page for JML
http://sourceforge.net/projects/jmlspecs
or directly from sourceforge.net
http://sourceforge.net/project/showfiles.php?group_id=65346
in the file JML.5.4.tar.gz. This is a gzipped tar file.

Some highlights of the release are summarized below. See the NEWS.txt
file in the release for other changes, including changes inherited
from the previous release of JML (more or less) and many bug fixes.
Highlights include:

- The tools can be run and installed under Java 1.5 (Java 5),
although the tools only parse and type check Java 1.4 source
correctly and jmldoc does not work under Java 1.5.
Thanks to Ovidio Mallo (and Werner Dietl). This solves
MultiJava bug 1092120.

- Improved support for Java 5 generics, especially addition
of wildcards and raw types. Thanks to Ovidio Mallo (and Werner Dietl).

- Fixed problem with parsing of nullity modifiers in
casts. Thanks to Patrice Chalin.

- The --nonnulltypes and -j options support a new feature for
"non null types". This includes a static analysis that
propagates nullity information. Thanks to Perry James and
Patrice Chalin.

New Release of JML, 5.3, is available

2006-05-17T12:28:44Z

Hi,

We've finally made the 5.3 release of the JML tools. This release is
available from from the sourceforge project page for JML
http://sourceforge.net/projects/jmlspecs
or directly from sourceforge.net
http://sourceforge.net/project/showfiles.php?group_id=65346
in the file JML.5.3.tar.gz. This is a gzipped tar file.

Some highlights of the release are summarized below. See the NEWS.txt
file in the release for other changes, including changes inherited
from the previous release of JML (more or less) and many bug fixes.
Highlights include:

- The non_null modifier is now the default on declarations,
including method arguments and results, and fields. A new
modifier keyword, nullable, was introduced to reverse this
default. One can accomplish the same thing by using the
type-level modifier "nullable_by_default", which reverts the
default back to the old one. There is a script,
bin-for-developers/addnullable that can be used to change a
type to be "nullable_by_default", as a quick way of using this
default. Thanks to Patrice Chalin.

- A new specification expression, \pre(E) can
be used in the body of a method (e.g., in an assert or in a
loop invariant) to refer to the pre-state value
of the expression E. This is preferred over the syntax,
\old(E), which can now also be used in the body of a method
with the same meaning. Similarly, the expression
\old(E, Label), can be used in the body of a method to refer to
the value of the expression E when control last reached the
label label in the method's current execution. These don't
work (in method bodies) in jmlc yet. This is feature request
998284. Thanks to Clyde Ruby for work on parsing and type checking.

- Added the new "code" modifier for heavyweight specifications and
model programs. Specification cases with the code modifier
generalize and replace the code_contract, which is now
deprecated. Such specification cases are only usable in
reasoning when it is statically know that the method's code is
being called, and are not inherited when the method is
overridden. This is feature request 1368585. Thanks to Clyde
Ruby for work on parsing and type checking. (This feature is
not yet implemented in the runtime assertion checker.)

- The accessible, callable, and measured clauses can now appear
in heavyweight specifications. Thanks to Clyde Ruby.

- Added the \same predicate keyword for requires clauses, so the
complete precondition from possibly many specification cases
do not have to be respecified, e.g., when the clauses in a
specification case are to apply to all other specification
cases. Thanks to Clyde Ruby.

- Added new keywords \only_accessed, \only_called, and
\only_captured, which can be used in postconditions. Thanks to
Clyde Ruby.

- The jmlc tool now does static checking of assignable clauses.
This fixes bug 1489974. Thanks to Cui Ye.

See the NEWS.txt file in the release for more details, bug
fixes, and incompatabilities with the previous release.

Please let us know your comments on JML, and if you find bugs.
You can now file bug reports from the sourceforge.net project page for
the jmlspecs project,
http://sourceforge.net/projects/jmlspecs
and you can see the bugs we know about there.

JML Release 5.3_rc4 (a minor bug fix over 5.3_rc3)

2006-01-11T21:40:56Z

Hi,

We've just made release candidate 5.3_rc4 of the JML tools. This release is
available from from the sourceforge project page for JML
http://sourceforge.net/projects/jmlspecs
or directly from sourceforge.net
http://sourceforge.net/project/showfiles.php?group_id=65346
in the file JML.5.3_rc4.tar.gz. This is a gzipped tar file.

Some highlights of the release are summarized below. See the NEWS.txt
file in the release for other changes, including changes inherited
from the previous release of JML (more or less) and many bug fixes.
Highlights include:

This release candidate fixes a bug in the files shipped for the
Universe type system in release candidate 5.3_rc3. Thanks to Werner
Dietl for fixing the bug.

We would still like testing of this to help evaluate the new non-null
default for declarations. If you are using JML for a class or are not
interested in such evaluation, you may want to want to wait for
another release of JML.

See the NEWS.txt file in the release for more details, bug
fixes, and incompatabilities with the previous release.

Please let us know your comments on JML, and if you find bugs.
You can now file bug reports from the sourceforge.net project page for
the jmlspecs project,
http://sourceforge.net/projects/jmlspecs
and you can see the bugs we know about there.

Re: Release candidate JML 5.3_rc3 available (needs testing)

2006-01-11T04:20:19Z

Hi Gary,

I just tried to build ESC/Java2 with this release candidate. It
looks pretty good to me so far.

Here are the results of this test:

o I am getting new warnings about references to the ghost fields like
"owner" as not being executable. E.g., the postcondition
//@ ensures \result.owner == null;
is not executable. Has something changed about ghost variables?

o Some bounded quantifiers in invariants are also not executable,
which I find strange. E.g.,
//@ invariant (\forall int i; (0<=i && i<count) ==> elements[i]!
=null);
where count is a private field of the same class. Several other
similar invariants are not compiling; typically, quantifiers bounded
by the length of an array.

All classes which previously could not be built due to bytecode jump
limitations are still failing to compile. E.g.,

Exception in thread "main" org.multijava.util.InternalError: INTERNAL
ERROR: target to far away
at org.multijava.util.classfile.JumpInstruction.computeEndAddress
(JumpInstruction.java:176)
...etc...

I have *not* yet tried *running* the compiled ESC/Java2, as I have to
first tweak lots of specs/headers, and I do not want to do that until
ESC/Java2 is running again on itself with non-null as a default.

Release candidate JML 5.3_rc3 available (needs testing)

2006-01-05T14:03:49Z

Hi,

We've just made release candidate 5.3_rc3 of the JML tools. This release is
available from from the sourceforge project page for JML
http://sourceforge.net/projects/jmlspecs
or directly from sourceforge.net
http://sourceforge.net/project/showfiles.php?group_id=65346
in the file JML.5.3_rc3.tar.gz. This is a gzipped tar file.

This release candidate needs some testing. I had some troubles with
the shell scripts under Linux, does anyone else see the same thing?
Also, we would like your opinon on the non_null-by-default feature
which is new in the release.

Some highlights of the release are summarized below. See the NEWS.txt
file in the release for other changes, including changes inherited
from the previous release of JML (more or less) and many bug fixes.
Highlights include:

- The non_null modifier is now the default on delcarations,
including method arguments and results, and fields. A new
modifier keyword, nullable, was introduced to reverse this
default. One can accomplish the same thing by using the
type-level modifier "nullable_by_default", which reverts the
default back to the old one. There is a script,
bin-for-developers/addnullable that can be used to change a
type to be "nullable_by_default", as a quick way of using this
default. Thanks to Patrice Chalin.

be used in the body of a method (e.g., in an assert or in a
loop invariant) to refer to the pre-state value
of the expression E. This is preferred over the syntax,

\old(E, Label), can be used in the body of a method to refer to

label label in the method's current execution. These don't
work (in method bodies) in jmlc yet. This is feature request
998284. Thanks to Clyde Ruby for work on parsing and type checking.

- Added the new "code" modifier for heavyweight specifications and
model programs. Specification cases with the code modifier
generalize and replace the code_contract, which is now
deprecated. Such specification cases are only usable in
reasoning when it is statically know that the method's code is
being called, and are not inherited when the method is
overridden. This is feature request 1368585. Thanks to Clyde
Ruby for work on parsing and type checking. (This feature is
not yet implemented in the runtime assertion checker.)

- The accessible, callable, and measured clauses can now appear
in heavyweight specifications. Thanks to Clyde Ruby.

- Added the \same predicate keyword for requires clauses, so the
complete precondition from possibly many specification cases
do not have to be respecified, e.g., when the clauses in a
specification case are to apply to all other specification
cases. Thanks to Clyde Ruby.

- Added new keywords \only_accessed, \only_called, and
\only_captured, which can be used in postconditions. Thanks to
Clyde Ruby.

fixes, and incompatabilities with the previous release.

New release of JML 5.3_rc2 available

2005-09-13T07:24:57Z

Hi,

We've just made release candidate 5.3_rc2 of the JML tools. This release is
available from from the sourceforge project page for JML
http://sourceforge.net/projects/jmlspecs
or directly from sourceforge.net
http://sourceforge.net/project/showfiles.php?group_id=65346
in the file JML.5.3_rc2.tar.gz. This is a gzipped tar file.

Some highlights of the release are summarized below. See the NEWS.txt
file in the release for other changes, including changes inherited
from the previous release of JML (more or less) and many bug fixes.
Highlights include:

- A new specification expression, \pre(E) can
be used in the body of a method (e.g., in an assert or in a
loop invariant) to refer to the pre-state value
of the expression E. This is preferred over the syntax,
\old(E), which can now also be used in the body of a method
with the same meaning. Similarly, the expression
\old(E, Label), can be used in the body of a method to refer to
the value of the expression E when control last reached the
label label in the method's current execution. These don't
work (in method bodies) in jmlc yet. Thanks to Clyde Ruby.

- Added the new "code" modifier for heavyweight specifications and
model programs. Specification cases with the code modifier
generalize and replace the code_contract, which is now
deprecated. Such specification cases are only usable in
reasoning when it is statically know that the method's code is
being called, and are not inherited when the method is
overridden. Thanks to Clyde Ruby.

- The accessible, callable, and measured clauses can now appear
in heavyweight specifications. Thanks to Clyde Ruby.

- Added the \same predicate keyword for requires clauses, so the
complete precondition from possibly many specification cases
do not have to be respecified, e.g., when the clauses in a
specification case are to apply to all other specification
cases. Thanks to Clyde Ruby.

- Added new keywords \only_accessed, \only_called, and
\only_captured, which can be used in postconditions. Thanks to
Clyde Ruby.
