[ https://issues.jboss.org/browse/JGRP-2271?page=com.atlassian.jira.plugin.... ] Bela Ban edited comment on JGRP-2271 at 6/15/18 3:59 AM: --------------------------------------------------------- Hmm, this is a bit more complicated than I thought: {{Socket.isConnected()}} returns true if is has been connected, even if it has been closed later! So the correct condition should be {{if(sock.isConnected() && !sock.isClosed())}} ! This is bad as {{Socket.isClosed()}} acquires {{sockLock}}, which is costly. I guess keeping a {{connected}} variable in {{Connection}} itself, which is set to true on successful connect and false on close, is our best option... was (Author: belaban): Hmm, this is a bit more complicated than I thought: Socket.isConnected() returns true if is has been connected, even if it has been closed later!
