> I've noticed that we are now receiving FinalModifierExceptions when running the samples (Blog and AriesTrader). It seems to me that these are the result of some changes for quiesce support for JPA. I'm not quite sure of the reason or purpose for the changes - but the function seems to be creating proxies for services using the AsmInterceptorWrapper for items that we did not previously create Asm proxies. Not all of these objects work well as proxies and hence these exceptions. This can be easily seen running either the Blog or AriesTrader samples after change rev. 995797 for ARIES-383 ( https://issues.apache.org/jira/browse/ARIES-383 )
