[jira] Created: (TRINIDAD-1062) ClassLoader exception when af:forEach is used with CLIENT_STATE_METHOD "all"

[My Faces - Dev mailing list]

ClassLoader exception when af:forEach is used with CLIENT_STATE_METHOD "all"
----------------------------------------------------------------------------

                 Key: TRINIDAD-1062
                 URL: https://issues.apache.org/jira/browse/TRINIDAD-1062
             Project: MyFaces Trinidad
          Issue Type: Bug
    Affects Versions: 1.2.7-core
            Reporter: Max Starets
             Fix For:  1.2.8-core
         Attachments: ObjectInputStream.diff

To reproduce, set CLIENT_STATE_METHOD to "all", and run a page with af:forEach that performs postback.

The following exception will be thrown:

2008-04-21 15:29:37.117
oracle.classloader.util.AnnotatedClassNotFoundException:

  Missing class: javax.servlet.jsp.jstl.core.IndexedValueExpression

Dependent class: java.io.ObjectInputStream
         Loader: jre.bootstrap:1.5.0_12
    Code-Source: unknown
  Configuration: jre bootstrap

This load was initiated at oc4j:11.1.1.0.0 using the Class.forName() method. The missing class is available from the following locations:

1. Code-Source:
/C:/JDEVADF_MAIN_GENERIC_080404.1239.4941/lib/java/shared/oracle.jstl/1.2/jstl
-api-1_2.jar (from <code-source> (ignore manifest Class-Path) in
/C:/jdevsystem/system11.1.1.0.22.49.41/o.j2ee/embedded-oc4j/config/server.xml)

     This code-source is available in loader oracle.jstl:1.2. This
shared-library can be made visible to the "oc4j" loader by modifying the boot
descriptor.

The issue is that ObjectInputStream created by CoreResponseStateManager uses default class loader instead of context class loader.

Andrew Robinson commented on TRINIDAD-1062:
-------------------------------------------

I am looking into this, and I do not see why this is needed

The JDK implementation of resolveClass uses the current class loader:

return VMObjectInputStream.currentClassLoader();

See http://docjar.com/html/api/java/io/ObjectInputStream.java.html  line 779

In http://docjar.com/docs/api/java/io/VMObjectInputStream.html you will see this is defined as:

Returns the first user defined class loader on the call stack, or the context class loader of the current thread, when no non-null class loader was found.

As you can see, the code should already be using the correct class loader. Is it possible that this is an OC4J bug? Does it reproduce in Tomcat or Jetty or only OC4J?

---------------------------------------

Haven't tried any container besides OC4J, so in theory this could be OC4J issue.

Max Starets commented on TRINIDAD-1062:
---------------------------------------

You were looking at the doc on GNU site. Sun's Javadoc is actually different. They do not mention context classLoader:

     * <p>The default implementation of this method in
     * <code>ObjectInputStream</code> returns the result of calling
     * <pre>
     *     Class.forName(desc.getName(), false, loader)
     * </pre>
     * where <code>loader</code> is determined as follows: if there is a
     * method on the current thread's stack whose declaring class was
     * defined by a user-defined class loader (and was not a generated to
     * implement reflective invocations), then <code>loader</code> is class
     * loader corresponding to the closest such method to the currently
     * executing frame; otherwise, <code>loader</code> is
     * <code>null</code>.

-------------------------------------------

I tested several different servers and here are my results:

apache-tomcat-6.0.16 - working
jboss AS 5.0.0.Beta4 - working
jetty 6.1.7 - working
JDev w/ OC4J development build 080501.0513.4973 - exception

Looks like it may be an OC4J issue
