> I was running a test with a WAB that uses JPA, and I found that the JPA entity contained in the WAB was not being enhanced. The reason was due to the following:
> 187 polo WARN [Blueprint Extender: 1] openjpa.Runtime - An error occurred while registering a ClassTransformer with org.apache.aries.jpa.container.unit.impl.PersistenceUnitInfoImpl@69b169b1. The error is logged along with this warning. Load-time class transformation will not be available.

> It turns out that the IllegalStateException is thrown because the WAB is in the RESOLVED state when a request for the BundleContext is made against it. The javadoc says "If this bundle is not in the STARTING, ACTIVE, or STOPPING states or this bundle is a fragment bundle, then this bundle has no valid BundleContext. This method will return null if this bundle has no valid BundleContext."
> Looking at the code in EntityManagerFactoryManager.bundleStateChange() I can see the following:
> public synchronized void bundleStateChange() throws InvalidPersistenceUnitException {
>
> switch(bundle.getState()) {
> case Bundle.RESOLVED :
> //If we are Resolved as a result of having stopped
> //and missed the STOPPING event we need to unregister
> unregisterEntityManagerFactories();
> //Create the EMF objects if necessary
> createEntityManagerFactories();
> break;
> //Starting and active both require EMFs to be registered
> case Bundle.STARTING :
> case Bundle.ACTIVE :
> if(tracker == null) {
> tracker = new ServiceTracker(bundle.getBundleContext(),
> "org.osgi.service.jdbc.DataSourceFactory", this);
> tracker.open();
> }
> registerEntityManagerFactories();
> break;
> //Stopping means the EMFs should
> case Bundle.STOPPING :
> //If we're stopping we no longer need to be quiescing
> quiesce = false;
> if(tracker != null) {
> tracker.close();
> tracker = null;
> }
> unregisterEntityManagerFactories();
> break;
> case Bundle.INSTALLED :
> //Destroy everything
> destroyEntityManagerFactories();
> }
> }
> This clearly shows that createEntityManagerFactories() gets driven when the WAB is in the RESOLVED state which results in the exception above. It looks like this should affect more than just WABs, but I have only hit this issue with WABs so far.
