> I got this just once when running integration tests on revision 1460730:
> NullPointerException: Specified service reference cannot be null.
> 	at org.apache.felix.framework.BundleContextImpl.getService(BundleContextImpl.java:458)
> 	at org.apache.sling.jcr.classloader.internal.ClassLoaderWriterImpl.getOrCreateClassLoader(ClassLoaderWriterImpl.java:215)
> and that line 215 is:
> final DynamicClassLoaderManager dclm = (DynamicClassLoaderManager) this.callerBundle.getBundleContext().getService(
>                 this.dynamicClassLoaderManager);
> looks like this.dynamicClassLoaderManager is unexpectedly null. 
> This happened while running org.apache.sling.launchpad.webapp.integrationtest.servlets.resolver.errorhandler.ErrorHandlingTest which installs JSP error scripts just before running, there might be a race condition here.
> I won't investigate further right now, cannot reliably reproduce, saving this info in case we see this again.
