Hi,some classes in jvmstat/perfdata code contains debug logging code predating the logging APIs, which
provokes some unnecessary allocation in certain applications.
Since the debug logging can't have been used for quite some time, I propose to remove it altogether
rather than converting it to the j.u.l. framework. bug: https://bugs.openjdk.java.net/browse/JDK-8028357 webrev: http://cr.openjdk.java.net/~redestad/8028357/webrev.01/ /Claes
