Hi Minoru,
IMHO the problem is caused by CustomThreadPool, where you execute the
same task in 2 threads simultaneously:
@Override public void execute(Runnable command){
if (command instanceof CallbackHandlerContextTask){
Context context = ((CallbackHandlerContextTask)command).getContext();
if (context != null && context.getCurrentOpType() ==
OpType.OP_CONNECT)
connectPool.execute(command);
}
super.execute(command);
}
probably you supposed to add "break" in if block?
Thanks.
WBR,
Alexey.
