Hi,
please review this test bug fix:

bug:
https://bugs.openjdk.java.net/browse/JDK-8065764
The test tested the mode "difference", according to the Javadoc:
If the counter difference mode is used, the value of the derived
gauge is calculated as the difference between the observed counter
values for two successive observations.
The test set the first value and then waited 2 times of
granularityperiod at line 171, hoped that the monitor would get the
first observation during this waiting time, but the test could fail
because granularityperiod * 2 was not enough and the test did the second
set before the monitor did the first observation.
It is easy to make the test timeout by commenting out the line 171.
The proposed solution is to get informed when the monitor did
observation on calling:
StdObservedObject.getNbObjects();
Thanks,
Shanliang
