Strange exception in Socket.accept. As a result I can't get a simple server that
accepts socket connections.

java.lang.IllegalMonitorStateException: current thread not owner
        at java.net.PlainSocketImpl.accept(PlainSocketImpl.java:150)
        at java.net.ServerSocket.accept(ServerSocket.java:107)
        at EchoServer.main(EchoServer.java:157)

Here is a more elaborate example: I've written server program (EchoServer)
and a client program (EchoTest). When running these on jakarta (my machine)
they work fine, but running them on tachyon they fail with the same error.

Here is how you run it on tachyon:

   > rsh tachyon.eng
   > cd ~avh/public_html/echo
   > java EchoServer

The server should say "Ready..." pretty soon.

On the same or another machine run the client program:


   > cd ~avh/public_html/echo
   > java EchoTest tachyon.eng foo bar

This will connect to the server which will then immediatly get an exception as described.
