/**
 * Returns the result of serializing and deserializing the given, exported
 * RemoteStub.//from  www.j  av a2 s  .  c  o m
 * <p>
 * Note, i'm leaving the paragraph below because i believe it is related to
 * the problem, however, adding the serialization cycle did <b>not</b> solve
 * the hard ref problem (hence that code is still in place).
 * <p>
 * Evidently, something special happens to a RemoteStub when it is
 * serialized.  There were previously issues during testing where
 * RemoteStubs were throwing NoSuchObjectException on the first remote call.
 * In these cases, the server objects were being garbage collected before
 * ever being used.  Eventually, I realized that this was because the
 * RemoteStubs were not being serialized in the test code (because both the
 * client and server are in the same VM).  There was initially a hack in the
 * RemoteStreamServer to get around this problem by temporarily maintaining
 * a hard reference to the server object until the client makes the first
 * successful call (which could cause leaks if the client dies before making
 * the first call).  After determining that the issue was due to
 * serialization, I was able to make the problem disappear by forcing a
 * serialize/deserialize cycle on the RemoteStub in the test code before
 * handing it to the client thread.
