Bulk closing tickets resolved in released versions

Keeping out of 4.2 – there were a few CI fixes that I'd rather not have in a minor release.

https://github.com/hibernate/hibernate-orm/pull/550

I have a work-in-progress with Pax Exam, Tinybundles, and Felix: https://github.com/brmeyer/hibernate-orm/tree/master-osgi-test

However, I hit a roadblock – documented in https://ops4j1.jira.com/browse/PAXTB-15. Classes are stripped of annotations when added to Tinybundles, which is obviously problematic for JPA.

I experimented with other hacky solutions, like attempting to force in a classloader that new where to look for the entity class and persistence.xml, but that sidesteps the entire concept of having a client bundle. For now, I'd like to hold off and do it correctly.

I took a stab at Arquillian, but hit many roadblocks – mainly having to do with lack of documentation or support around embedded containers for standalone tests. This thread began to discuss it: http://lists.jboss.org/pipermail/jboss-osgi-dev/2013-June/000349.html
