test/sun/management/HotspotRuntimeMBean/GetSafepointSyncTime.java is no longer reproducible on jdk8 b109. But it still fails with 7u45. There might be a hotspot fix in jdk8 that resolves the zero safepoint sync time issue.

This adds the safepoint count in the test to find out if safepoint does occur. Also take GetSafepointSyncTime.java from the ProblemList.txt.
