[PATCH 5062/7508] Metrics???: fix a bug that froze jvm memory stats Motivation: a bug was discovered that caused Jvm memory stats to never update Modification: I added an interface MemoryReporter that has a getUsage() method to refresh the memory, and reframed memory usage on that method. Results: Memory usage should now update when stats are resampled
