Chetan Sarva commented on AMQ-2290:
-----------------------------------
Sorry, I should have captured the column headers as well. The 3 columns are:
shallow heap (bytes), retained heap (bytes), and percentage. I don't believe
there are multiple instances of the LRUCache itself in this case, however there
are 650,113 entries in the map.
> Memory leak in SelectorParser LRUCache

> Key: AMQ-2290
> URL: https://issues.apache.org/activemq/browse/AMQ-2290
> Project: ActiveMQ
> Issue Type: Bug
> Components: Selector
> Affects Versions: 5.3.0
> Reporter: Chetan Sarva

>
> There appears to be a memory leak in the LRUCache used by the SelectorParser.
> We have a simple selector-based request/response implementation which means
> we create a new selector on every request and these appear to be sticking
> around despite the use of an LRUCache with a 10,000 entry limit. A quick look
> at the LRUCache code didn't reveal any obvious problems, so I'm not sure
> what's going on here. For the time being we are rolling back to 5.2.
