RE: [aspectj-users] Compatibility?

[Jim Bethancourt <jimbub2002@xxxxxxxxx>]

Hi fellas,
I noticed on the AOSD conference website that Jonas
Bonér, who is giving a presentation on AspectWerkz, is
a developer on the JRockit JVM for BEA, so maybe he
could provide some insight and some help.  After a
little bit of hutning, I found an email address he
uses:  jboner@xxxxxxxxxxxx

Don't know if this will help much, but it's worth a
shot. 

Yours truly,
Jim
