It would be really really great to have more eyes on the tck.
This particular problem seems to be due to an interaction between geronimo and
openejb. In geronimo the classloader that the proxy is attached to is a
wrapper for the osgi bundle and doesn't actually load any classes itself. So
once the proxy is attached to that classloader it becomes completely
inaccessible.
I'm changing the code involved to use the original proxied class's classloader
and protection domain. So far I don't see any problems in geronimo or openejb.
Class<?> cls = (Class<?>) unsafe.defineClass(proxyName, proxyBytes,
0, proxyBytes.length, clsToProxy.getClassLoader(),
clsToProxy.getProtectionDomain());
I've opened https://issues.apache.org/jira/browse/OPENEJB-1321 to provide a
hook for any problems this may cause. I'd really appreciate some review and
informed criticism.
many thanks
