A patch from Philippe Mouawad "OutOfMemory provoked by Cache overflow" (https://issues.apache.org/jira/browse/OFBIZ-2186) - OFBIZ-2186
CacheLineTable and LRUMap do not synchronize on the same lock
* CacheLineTable synchronization use the CacheLineTable instance monitor
* LRUMap synchronization use the LRUMap instance monitor
the LRUMap (memoryTable) can be updated concurrently by 2 differents threads
* one in the CacheLineTable #put or CacheLineTable#remove
* another in the CacheLineTable#get
this leads to the corruption of the LRUMap which is not thread-safe
the CacheLineTable#get should be synchronized or the LRUMap should be replaced by a thead safe collection
