"org.apache.openjpa.persistence.TransactionRequiredException: There is no managed transaction in progress to sync this EntityManager with" - deploying in fabric

[pgfox]

Sometimes seeing

org.apache.openjpa.persistence.TransactionRequiredException: There is no managed transaction in progress to sync this EntityManager with.

It seems that the start order of the bundles are causing this exception. In fabric (JBoss Fuse 6.1) the only way to influence start order is to import/export OSGi services between bundles.

adding a pull request with sample update that worked around the issue.
