Please, review the following simple change Issue : https://bugs.openjdk.java.net/browse/JDK-8029098 Webrev: http://cr.openjdk.java.net/~jbachorik/8029098/webrev.00
The 'ListenerScaleTest' is meant to check the proper scaling of the MBean notification dispatching. This doesn't make much sense for fastdebug builds where all the timing is rather skewed.
The patch checks for the fastdebug build and just skips the test and outputs a notification message.
Thanks, -JB-
