Andrey Gura commented on IGNITE-1820:
-------------------------------------
The problem is {{GridServiceProcessor}} doesn't complete
deployment/undeployment futures. So deployment initiator thread ({{Thread-3 in
thread dump below}}) is waiting for future completion while {{DestroyJavaVM}}
thread waiting for termination of all non daemon threads.
