Connection.close() taking 2 minutes in JBossMQ

For some reason I haven't investigated Thread.interupt() is not interupting I/O reads.

The JBossMQ UIL2 does this to stop the ReadTask which in turn closes the socket.

This can be see in the following test run:
http://cruisecontrol.jboss.com/cc/artifacts/jboss-4.2-testsuite-sun-1.5/20070716040519/results/index.html
where some tests are timing out or taking 2 minutes.

Without the interuppted I/O the ReadTask will wait until the "Read Timeout" (default 2 minutes)
to end because at this point the client has stopped pinging.
