The hsperf counter was "ParNew:CMS", but now it is "ParNew::CMS". It should still use single colon as ParallelGC and SerialGC still use the value "ParScav:MSC" and "Copy:MSC".
Verifying is easy:
$ java -XX:+UseConcMarkSweepGC -XX:PerfDataSaveFile=test.hsperf -version >& /dev/null; strings test.hsperf | grep -C 2 "sun.gc.policy.name"
sun.gc.lastCause
No GC
sun.gc.policy.name
ParNew::CMS
sun.gc.policy.collectors
$ java -XX:+UseParallelGC -XX:PerfDataSaveFile=test.hsperf -version >& /dev/null; strings test.hsperf | grep -C 2 "sun.gc.policy.name"
sun.gc.generation.1.space.0.used
sun.gc.generation.1.space.0.initCapacity
sun.gc.policy.name
ParScav:MSC
sun.gc.policy.collectors
