Ramesh Reddy commented on JBCACHE-1571:
---------------------------------------
I am trying to use JBC in Teiid project, I ran into exact same issue. It looks like, ClusteredCacheLoader is created reflectively, but it expects a injection of the command factory, which never gets set thus the NPE. Can anybody offer any solutions?
