Hello,
Could you advise for me about this problem.

When I use session.write , it happened deadlock.
I don't know why~
> this is some sample about multicast.
public void multicast(String channelName, Object message) {
if (!(message instanceof ByteBuffer)) {
return;
}
ByteBuffer rb = (ByteBuffer) message;
// try{
GameRoom channel = RoomManager.getRoom(channelName);
List list = (List) channel.getUsers();
Iterator it = list.iterator();
while (it.hasNext()) {
ByteBuffer buf = rb.duplicate();
User user = (User) it.next();
WrteFuture future = users.getSession().write(buf);
future.join();
}
rb.release();

[jira] Commented: (DIRMINA-241) When I used session.write(message),

Trustin Lee commented on DIRMINA-241:
-------------------------------------
It seems like the deadlock occurred because you tried broadcasting messages to multiple sessions. Two sessions were broadcasting messages to each other and it caused the deadlock in SSLFilter. Please try to send messages in a dedicated background thread for now, or disable SSLFilter temporarilly. We need to find out the best solution for this issue.
