Subject Re: [jira] [Created] (ARIES-933) IllegalStateException when the peristence bundle gets resolved.
Date Fri, 05 Oct 2012 10:07:23 GMT
Hi Ioannis,
We have attempted this before. However, this will cause some other app
server to fail as they need EMF to perform entity enhancement using a
mechanism other than using ByteCodeWeaving.
See jira https://issues.apache.org/jira/browse/ARIES-832 for more details.
Thanks
Emily
