Jaakko Laine commented on CASSANDRA-634:
----------------------------------------
Very strange one.
Line 146 in FailureDetector is this:
EndPointState epState = Gossiper.instance().getEndPointStateForEndPoint(ep);
According to the stacktrace it does not even reach getEndPointStateForEndPoint,
and even if it did, ep comes from InetAddress.getByAddress, so it cannot be
null. Also, if the culprit was Gossiper constructor, that should also show in
the trace.
This would mean that Gossiper.instance() returns null, but I don't know how
that can happen. "volatile" in gossiper_ is actually not needed, but I don't
know if having it there could cause such thing. "volatile" was added here
pretty recently, so it just might be one possible explanation why this came up
now.
BTW what version of java you're using?
