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?
When undo() operation from t3 called more times than insertString() and 
remove() in t1 and t2. Note that undoOrRedo() in t3 is also may work as 
undo().
