Felix Meschberger commented on SLING-2617:
------------------------------------------
That's exactly the problem. I have a fix for the problem in the JCR Classloader
bundle as follows:
(a) The ClassLoaderWriterImpl class binds the DynamicClassLoaderManager service
reference instead of the service itself
(b) The ClassLoaderWriterImpl is a service reference component. Thus it has
access to the calling bundle
(c) Using the calling bundle's bundle context the ClassLoaderWriterImpl can
then get the DynamicClassLoaderManager service and create the
RepositoryClassLoader.
This is easy to implement because the ClassLoaderWriterImpl instances will be
created in parallel for the DynamicClassLoaderManager service instances thanks
to how service factories work in OSGi. We just have to make sure to unget the
DynamicClassLoaderManager service once we destroy the RepositoryClassLoader.
(for proper resource management)
