Please, review the following test change Issue : https://bugs.openjdk.java.net/browse/JDK-8081634 Webrev: http://cr.openjdk.java.net/~jbachorik/8081634/webrev.00
This is an issue in the utility class providing the functionality to run the 'jcmd' command and parse its output. The jcmd command output is being captured in a separate thread and fed to a shared StringBuilder instance. StringBuilder not being synchronized this might lead to intermittent failures due to (mostly) the write visibility. The fix is to use StringBuffer which is the appropriate class for this kind of usage.
Thanks, -JB-
