I have a maven project set up to test this, and I get consistent results.  Here
are the problems:

1. I have a multi-module which has one module which must be built before any
other modules, and another module that must be build after all other modules are
build.   All the other modules can be built in parallel after the first module
builds.  When I build this with the "Build modules in parallel" option checked
for the project, it correctly runs the first module, then loads other modules up
in the build queue.  However, when all modules have been loaded into the queue,
it will then add the last module to the queue before all the other modules have
completed their builds.  The dependencies are all set up in the pom.xml file.
It works correctly with the  "Build modules in parallel" option not checked.  It
seems as if the dependencies are checked and loaded based on dependant modules
being loaded into the build queue rather than when their builds complete.

2. This seems strange that it would be related, but again, I can reproduce this
at will. Reading of environment variables for parameterized builds doesn't work
when the "Build modules in parallel" option is checked. Using the
maven-antrun-plugin, I have a line defined as <echo message="Reference=${REF}"/>
under the <tasks> tag.  With the "Build modules in parallel" unchecked, it works
fine and I get the value I enter when I start the build.  However with the
"Build modules in parallel" checked, The value comes back as ${REF} rather than
the value.

Your help on these two issues would be much appreciated.  Using the  "Build
modules in parallel" is not usable if I have dependencies or need parameters in
my project.  The third item below is not as critical.


3. The blinking status icons on the project page behave strangely when the
"Build modules in parallel" option is checked.  When I start up a project
build,and go back to the Dashboard, The Icon either doesn't blink at all.  There
is no feedback at all during the build.  Even if I have a module that fails
making the Icon red, when I start the build, it immediately turns blue for the
duration of the build, and then turns red again when the build fails again.  

Thanks for your help
