  32  * Test case for bug #97697#.
  33  *
  34  * <p>Bug #97697# "GPF in java-uno bridge in bugdoc scenario" shows that sending
  35  * a plain <code>Object</code> as an <code>Any</code> over the URP bridge lead
  36  * to a <code>StackOverflowError</code> on the writer thread, which was silently
  37  * discarded (and the bridge was not disposed).</p>
  38  *
  39  * <p>This test has to detect whether the spawned client process indeed hangs,
  40  * which can not be done reliably.  As an approximation, it waits for 10 sec and
  41  * considers the process hanging if it has not completed by then.</p>
