server log

Description of problem: When I do inventory/uninventory of any resource I get ConcurrentModificationException in server's log.


Version-Release number of selected component (if applicable):
Version: 4.3.0-SNAPSHOT
Build Number: 3d0d044

How reproducible: always


Steps to Reproduce:
1.have some resource (I have EAP6 ER1 standalone server) under platform in discovery queue
2.inventory it
3.uninventory it
4.run manual autodiscovery
5.inventory it again
  
Actual results: There is an exception in log (see attachement). Not sure if it happens in step 3 or 5. 


Expected results:


Additional info:If I run autodiscovery on agent afther this exception was fired, it becomes 'In progress' for unusual amount of time, afer that whole platform and all resources become down. It does not seem to be related to EAP6 plugin, it happens for each resource.
