Memory leak in DestinationContainer [JMS] - NW 7.4

Hello!

We have a problem with possible memory leak in DestinationContainer. This class is parts of JMS component. I found that this issue is very similar to issue described in SAP note (1919681 - Prevent OutOfMemory error in JMS destination container).

In our case, NW stack is in SP 10 (7.4010.2015***). So I expect that the problem is fixed (SAP note fix it in SP 06).

I attached some pictures from heap analysis:

Huge amount of memory is used in waitingForMessagesConsumers (a member of QueueDestinationManager). This hash map contains more than 2 400 000 hash items. It's this expected state or it's memory leak.

Thanks.
