  35 /* This test attempts to stymie the RMI accept loop.  The accept loop in
  36  * RMI endlessly accepts a connection, spawns a thread for it, and repeats.
  37  * The accept() call can be replaced by a user-supplied library which
  38  * might foolishly block indefinitely in its accept() method, which would
  39  * prevent RMI from accepting other connections on that socket.
  40  *
  41  * Unfortunately, HttpAwareServerSocket (default server socket) is/was such
  42  * a foolish thing.  It reads 4 bytes to see if they're "POST" before
  43  * returning.  The bug fix is to move the HTTP stuff into the mainloop,
  44  * which has the side effect of enabling it for non-default socketfactories.
  45  *
  46  * This test:
  47  * 1. Creates an object and exports it.
  48  * 2. Connects to the listening RMI port and sends nothing, to hold it up.
  49  * 3. Makes a regular call, using HTTP tunnelling.
  50  * 4. Fails to deadlock, thereby passing the test.
