I fully agree that the javaagent has plenty of issues (both inOpenJPA, but mostly in Java itself) and shall only be used as last resort.

But I hope TomEE doesn't do any CMP processing anymore, isn't? That would be a shame, as CMP got ditched a long time ago and is not part of the EE6 WebProfile afaik, isn't?
