Subject Re: Java client: Cannot stop during failover ?
Date Fri, 26 Jul 2013 13:39:39 GMT
Connection.stop() and close() don't seem to help.

Returning false from preFailover() is not a solution because that is invoked
once before the start of a failover, but my problem is when the failover is
already started when you try to shut down.

I'm starting to think I'll have to give up with the automatic failover, and
implement a reconnection logic myself...
