Hi to all, We are trying run Jackrabbit garbage collector on scheduler. Jackrabbit deployed under GF 3.0.1 using JCA. The code is following: JCASessionHandle jcaSession = (JCASessionHandle) getSessionFactory().getSession(); SessionImpl session = (SessionImpl) jcaSession.getWorkspace().getSession(); gc = session.createDataStoreGarbageCollector(); On the first line always exception appears: java.lang.ClassCastException: org.apache.jackrabbit.jca.JCASessionHandle cannot be cast to org.apache.jackrabbit.jca.JCASessionHandle Any idea?! Regards, Anton
