Sharan Foga updated OFBIZ-4222:
-------------------------------
Sprint: Bug Crush Event - 21/2/2015
> UtilCache has memory leak if many temporary caches are created
> --------------------------------------------------------------
>
> Key: OFBIZ-4222
> URL: https://issues.apache.org/jira/browse/OFBIZ-4222
> Project: OFBiz
> Issue Type: Bug
> Components: framework
> Affects Versions: Trunk
> Reporter: Philippe Mouawad
> Assignee: Adam Heath
> Labels: CACHE, LEAK, MEMORY
>
> Since some time UtilCache has been updated to replace the WeakHashMap by a
> ConcurrentHashMap:
> private static final ConcurrentHashMap<String, UtilCache<?, ?>>
> utilCacheTable = new ConcurrentHashMap<String, UtilCache<?, ?>>();
> I think this fix to concurrency issues has introduced a memory leak or at
> least a much bigger impact on Memory.
> Indeed descendent of AbstractCache (particularly
> AbstractEntityConditionCache, EntityListCache) tend to create many caches
> that do not need to always persist in time.
> The old WeakHashMap handled this by enabling them to disappear while today
> the Hard ref disables this.
