Problem to invoke createDataStoreGarbageCollector() in JCASessionHandle object

It's imposible to execute the followin code:

import org.apache.jackrabbit.core.data.GarbageCollector;
...
GarbageCollector gc;
SessionImpl si = (SessionImpl)session;
gc = si.createDataStoreGarbageCollector();

// optional (if you want to implement a progress bar / output):
gc.setScanEventListener(this);
gc.scan();
gc.stopScan();

// could be a separate button, if multiple repositories use the same data store:
gc.deleteUnused();

It throws a ClassCastException, because with JCA, the session object is of type JCASessionHandle.

I have solve this bug by changing the private method getSession() of the JCASessionHandle class to public.

CURRENT IMPLEMENTATION:
private Session getSession() {
return mc.getSession(this);
}

MODIFICATION:
public Session getSession() {
return mc.getSession(this);
}

And the final code look's like this:

SessionImpl si = (SessionImpl)((org.apache.jackrabbit.jca.JCASessionHandle)session).getSession();

¿There are other solution more clean?
