[Engine-devel] Moving to Jboss AS7

Mon Feb 6 15:10:07 UTC 2012

Hey,

Yes, I'm aware of that issue.
The reason we chose to work with Beta1b is due to several regressions in resteasy 2.3.1 (Beta1b ships with resteasy 2.2.3).

In the next AS version those issues are supposed to be fixed, and then we'll work with it upstream.
If you are curios in understanding the standalone.xml changes you can take a look at this patch:
http://gerrit.ovirt.org/#change,715

It contains both changes in standalone.xml, and removal of the jboss naming jar from our repo (it was there due to an issue in LDAP on beta1b, that was fixed in CR1b).

Thank you,
Oved
