/* @test
* @bug 4322806 8189338
* @summary When an RMI (JRMP) connection is made to a TCP address that is
* listening, so the connection is accepted, but the server never responds
* to the initial JRMP handshake (nor does it terminate the connection),
* the client should not hang forever; instead, it should throw an exception
* after a reasonable timeout interval. The exception should be a
* java.rmi.ConnectException or ConnectIOException, not a MarshalException,
* because it should be clear that no partial call execution has occurred at
* this point (because no data for the invocation has yet been written).
