This code below strikes me as possibly being in the wrong order. If you
interrupt a thread, it should bail. But if you close the socket, it
should do the same thing, and close the socket too (I'm pretty sure
there's a handshake for TCP for "close me".)
Interrupting a thread just sets a flag. It doesn't do anything unless
it runs across a method call that will throw an InterruptedException
If you interrupt the thread, then close the socket, the "close" might
never happen. I'd *just* close the socket, if that passes your testing.
Try to let the thread actually execute the close, and then unwind
(I didn't look to see if your thread/runnable has other places it waits
besides the socket. If it does, those should be eliminated, replaced
with other sockets which are also closed, etc.)
Not sure what you mean here. The thread waits on the BufferedReader but
closing the socket closes the stream which should cause an IOException.
The server end closing the stream should cause the read to return null
and the code should print the End of Stream message which it doesn't so
I don't think that is where it is getting hung up.
