libjamm-java - 0.3.3-3 main

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.
