SocketAcceptor.unbind can hang when unbinding only one of several service adresses ----------------------------------------------------------------------------------
Key: DIRMINA-722 URL: https://issues.apache.org/jira/browse/DIRMINA-722 Project: MINA Issue Type: Bug Affects Versions: 1.0.10 Environment: Centos 5.3, JDK 1.6.0u11 Reporter: Rhys Yarranton If a SocketAcceptor - has multiple service addresses bound and - you unbind one of them and - disconnectOnUnbind is true and - the one being unbound has at least one session connected and - some other session on the acceptor also has at least one session connected the unbind call can hang. Excerpt from stack trace below. I suspect the hang is coming from IoServiceListenerSupport.disconnectSessions. The sessions to be closed are in the sessions variable, which is a subset of managedSessions (line 280). However, at lines 306-309, it is waiting (forever) for managedSessions to be empty. This will never happen. This is 1..0.10. The 1.1.7 code is different (it uses a countdown latch), and looks OK.
