Short description: JVM core dumps in ClassLoader.defineClass0().

Full problem description: 

We are running JBOSS 3.2.1.  When we have duplicate class, we get the following error message 
              java.lang.LinkageError: duplicate class definition:
    com/nortel/mftP/dmlP/modelP/faultP/workflowP/AlarmClearWorkflowC

and shortly after the JVM core dumps. However, we dont see this
behavor with J2SE 1.4.0 or 1.4.1_05. This is 1.4.2 specific.

EVALUATION This may be a duplicate of 4846301. Thanks Jane.. ###@###.### 2003-09-24 The following sequence will lead to such a crash: 0) loader1 loads and defines B. 1) Class C which extends B is loaded from resolve_instance_class_or_null() by loader 2. 2) A placeholder (C, loader2) is added to the system dictionary. 3) loader 2 loads C and defines C, which in turn resolves B, C's super class, in resolve_super_or_fail(). 4) loader 2 delegates the loading of B to loader1, which loads B and tries to define B. However, loader1 has defined B before, so a "duplicate class definition" LinkageError is thrown. 5) The exception will make the placeholder (C, loader2) removed in resolve_from_stream(). Because loader2 fails to define C. 6) loader2's loadClass() however, catches the exception and redelegates to another loader to finish the loading of C. 7) resolve_instance_class_or_null() is later surprised to find that the placeholder (C, loader2) is removed (actually by its own thread!). The code since 1.4.2 will crash in this case. A testcase containing the above sequence is attached. ###@###.### 2003-09-26 The fix changed the behavior back to that of 1.4.1, i.e. always update the system dictionary even if the placeholder is removed. ###@###.### 2003-10-10
