ISPN-5104 Infinite loop in TransactionAwareCloseableIterator when
iterating through cache

Fixed issue where entry was repeated if added to context after
starting a transaction
Replace sfl4j-jdk14 dependency with sfl4j-log4j12 so that jboss logging
writes to log4j in the cdi module (and dependents).

Add more debugging around cache listeners. It seems Class.getMethods()
sometimes returns synthetic methods created by overriding a generic method.
