NIO TLS blocks on socket establishment for 10 seconds #115

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
When trying to send message to destination that does not have established 
socket and is not reachable , sip stack gets blocking , thats because of usage 
of :
NioTcpMessageProcessor.blockingConnect

the exception posted below :

It should not block and allow the code proceed.
In case of socket establishment failure IOExceptionEvent may be thrown

Sorry , pointed to invalid function.

NioTcpMessageProcessor.initiateConnection has the following code :

socketChannel.socket().connect(address, timeout);
socketChannel.configureBlocking(false);

so first it tries to connect to other side and then configure blocking to false 
( non blocking )

Is there any workaround for this?
