Christian Schneider commented on ARIES-1181:
--------------------------------------------
I just checked your example code. The problem is that you define the data
source in the blueprint that also needs the EntityManger. The blueprint context
will only be initialized when the EntityManager is present. This will not
happen though as jpa container will wait for the data source to show up. So you
run into a timeout. Try to define the data source in a separate bundle.

> 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

> 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.
