Subject Re: javax.persistence.EntityListeners is never called
Date Fri, 17 Oct 2014 15:01:58 GMT
I don't see your patch... and I also don't see this same problem when
running in Eclipse.

What vendor / version of java are you running? I remember seeing similar
problems when running with early version of java 7 (or maybe it was 8.. I
don't really remember)

Is your original problem resolved?
