Unfortunately, since the output > of _entityMgr.findById is not checked this means that Null Pointer Exceptions > are generated when trying to access the output for expunged VMs. > The attached patch fixes the issue and applies a similar fix for other > similar cases. -- This message was sent by Atlassian JIRA (v6.2#6252)
