Matt Sicker commented on ARIES-1181:
------------------------------------
Would this still work with JPA 2.1? The blueprint standard isn't very clear on
that (it just mentions 1.0 and 2.0).
> Getting a NullPointerException trying to instantiate JPA-related classes

> Key: ARIES-1181
> URL: https://issues.apache.org/jira/browse/ARIES-1181
> Project: Aries
> Issue Type: Bug
> Components: Blueprint
> Environment: ServiceMix 5.0.0, Mac OS X 10.8.5, Oracle Java 1.7.0_40,
> EclipseLink 2.5.1, JPA 2.1
> Reporter: Matt Sicker
> Priority: Blocker

> Due to the JPA blueprint component not supporting JPA 2.1, I thought that I

> However, no matter how I try to configure it, I get an NPE with no useful
> debugging information available. I'm able to configure a JDBC data source on
> its own, so I know it's related to the entity beans.
