Description Ivo Studensky 2013-09-27 09:18:51 UTC 
Description of problem:
RemoteDomainConnection.close() overrides FutureManagementChannel.close() to first send a "unregister" message to the master HC before calling the superclass functionality.

Problem is this call tries to open a connection to the master and will block forever waiting for it to connect if the master isn't available, as seen at http://fpaste.org/18232/37105700/

That example was from AutoIgnoredResourcesDomainTestCase which is concurrently shutting down the hosts in the domain, meaning the master can be shutting down in the middle of or prior to slave shutdown.


A backport of WFLY-1511 to EAP 6.2.
