Rick, Sorry about the delayed response, but setting "Can-Retransform-Classes: false" in the manifest file *did* fix the problem.
Apparently, the IBM JRE does not support runtime class re-transformation (which you probably already know). Based on this information, I'm assuming that it would be a best practice to manually run "org.apache.openjpa.enhance.PCEnhancer" if you are expecting to run with the IBM JRE so that OpenJPA can take advantage of the enhanced classes for the IBM JRE, correct? Also, apparently you can query the JRE to determine it's capabilities via the http://download.oracle.com/javase/1.5.0/docs/guide/jvmti/jvmti.html#GetCapabilities JVM TI . This would allow you to determine (at runtime) if the JRE was capable of class re-transformation; however, I suspect you'd have to write a JNI interface to get to it which might not be acceptable for a pure Java solution.
