Java Agent for Memory Measurements
Jamm provides MemoryMeter, a java agent to measure actual object memory use including JVM overhead.
MemoryMeter is as accurate as java.lang.instrument.Instrumentation.getObjectSize, which only claims to provide "approximate" results, but in practice seems to work as expected.
MemoryMeter uses reflection to crawl the object graph for measureDeep. By default, MemoryMeter keeps track of descendants visited by measureDeep with an IdentityHashMap.
