manager A couple of questions about this: 1. the first evictAll() seems to be clearing the L2 cache ... is a bit tricky. pmf.getDataStoreCache().evictAll() clears the L2 cache . pm.evictAll() clears the persistence manager (L1) cache . But evictAll does not affect objects that have been changed by the current
