Hello,

Please review fix for JDK9:

bug: https://bugs.openjdk.java.net/browse/JDK-8145787
webrev: http://cr.openjdk.java.net/~ssadetsky/8145787/webrev.00/

This is a multithreading stress test in which the undo queue depth may reach zero sometimes occasionally. The corresponding checks were added.

    What is the sequence of the threads leads that the exception is thrown?

   Thanks,
   Alexandr.
