Alena Prokharchyk commented on CLOUDSTACK-84:
---------------------------------------------
See my comments to the reviewboard ticket. The problem is completely different
now, no NPE is hit in this case and the patch suggested won't fix anything. The
problem is, when account/project cleanup thread runs, the userContext.caller
should have been System account as for this type of the account we don't even
do a permission check. But in this case the caller is somehow Account[3-user1],
therefore the permission check fails. Once incorrect context problem is called,
the router/network will be removed w/o any problems.
