[jira] Commented: (HIVEMIND-120) Proxy creation failure for non-interface beans
[ http://issues.apache.org/jira/browse/HIVEMIND-120?page=comments#action_64821 ]
Brian K. Wallace commented on HIVEMIND-120:
-------------------------------------------
Although the test case I attached earlier is still valid, I've narrowed the problem down to "public final" methods in parent classes and can produce the same error by creating a simple (not extending any other class) bean with a method "public final sayHello() {}". Attempts to wrap this in a proxy will undoubtedly fail wrapping a final method.
