I suggest that this test is failing, so you are writing nothing and 
immediately closing the socket, hence the immediate read() returning -1 
at the receiver. I would print a trace if this test fails, as surely you 
want to know about invalid source addresses, as well as debug this
problem.

Wrong. You should always close the outermost output stream of the 
socket, and closing a socket or its output stream or its input stream 
closes the other two.

The s.isClosed() test here is pointless, unless you have another thread 
that might close the socket. It won't tell you when you have reached 
EOF. read() returning -1 tells you that.

See above. Close the output stream only.
