Description of problem: There are a few changes in JCA tests in the upstream which make them more stable. The tests, however, still show some instability especially in PartialObjectActivationJarTestCase, see WFLY-1560, which is going to be fixed soon. The reason for this bug is that we need to sync the code of JCA tests before new fixes comes.
Created a PR for this: https://github.com/jbossas/jboss-eap/pull/187
This one has been merged to 6.1.1 actually, but its status was not changed.
Merged and JCA tests indeed seem to be more stable.
