JDK6 Update 23 changes CMS Collection counters

Stefan Frandl, Test Automation Team Lead at Dynatrace, recently tested an upgrade of our Dynatrace platform from JDK6u21 to JDK6u23. He discovered a change in Garbage Collection MXBean Counters that changes the way we monitor Runtime Suspensions caused by GC Activations. More details on the actual changed counters and a follow up link to an Oracle Forum on the dynaTrace Community Portal.
