FULL JDK VERSION(S)
Sun Java 5.0 - from inspection of code only
IBM Java 5.0 build from stress test run
DESCRIPTION:
Implementation of cbEarlyException in debugInit.c includes the fragment
    error = classSignature(clazz, &signature, NULL);
    if ( (error==JVMTI_ERROR_NONE) &&
        (strcmp(signature, initOnException) == 0)) {
        LOG_MISC(("Initializing on specific exception"));
        initialize(env, thread, EI_EXCEPTION);
        jvmtiDeallocate(signature);
    } else {
        error = JVMTI_ERROR_INTERNAL; /* Just to cause restore */
    }
The classSignature funtion causes JVMTI to allocate memory for a class signature. However, the
jvmtiDeallocate call to release it is only run if it was allocated successfully AND the signature
matches the initOnException string. If the signature does NOT match the initOnException string,
it is never freed.
This is easy to verify on an IBM build, using IBM trace. Without this you could put a printf in
jvmtiDeallocate and classSignature (both in util.c) and run the command:
java -Xint -Xrunjdwp:transport=dt_socket,server=y,onhrow=foo.bar,launch=echo NoSuchClass <- non-existent class
You will see allocations without matching frees.
