Log:
[JBCACHE-1582] (ExpirationAlgorithm doesn't evict nodes that have been created in a long Tx) Pass command and transactional information to the eviction algorithm in order to find out expiration time and whether the call is transactional. This allows eviction transaction expiration tree nodes to be delayed until they've been committed and resolves a memory leak.
