- *
- * @summary RMI blocks in HttpAwareServerSocket.accept() if you telnet to it
- * @author Adrian Colley
- *
- * @library ../../../../../java/rmi/testlibrary
- * @modules java.rmi/sun.rmi.transport.proxy
- * @build TestIface TestImpl TestImpl_Stub
- * @run main/othervm/policy=security.policy/timeout=60 BlockAcceptTest

-
-/* This test attempts to stymie the RMI accept loop. The accept loop in
- * RMI endlessly accepts a connection, spawns a thread for it, and repeats.
- * The accept() call can be replaced by a user-supplied library which
- * might foolishly block indefinitely in its accept() method, which would
- * prevent RMI from accepting other connections on that socket.
- *
- * Unfortunately, HttpAwareServerSocket (default server socket) is/was such
- * a foolish thing. It reads 4 bytes to see if they're "POST" before
- * returning. The bug fix is to move the HTTP stuff into the mainloop,
- * which has the side effect of enabling it for non-default socketfactories.
- *
- * This test:
- * 1. Creates an object and exports it.
- * 2. Connects to the listening RMI port and sends nothing, to hold it up.
- * 3. Makes a regular call, using HTTP tunnelling.
- * 4. Fails to deadlock, thereby passing the test.
- *
- * Some runtime dependencies I'm trying to eliminate:
- * 1. We don't know the port number until after exporting the object, but
- * have to set it in http.proxyPort somehow. Hopefully http.proxyPort
- * isn't read too soon or this test will fail with a ConnectException.
