Doing the currentThread call on the Java side was necessary due to the difficulty of getting the current thread while inside one of these Tracker native methods. This class lives in rt.jar. *Byte Code Instrumentation(BCI) Using the ClassFileLoadHook feature and a C language implementation of a byte code injection transformer |

| is injected All classes found via ClassFileLoadHook are injected with the exception of some system class methods< init > and finalize whose length is and system class methods with name< clinit > and also java lang Thread | currentThread () which is used in the class Tracker(preventing nasty recursion issue). System classes are currently defined as any class seen by the ClassFileLoadHook prior to VM_INIT. This does mean that objects created in the system classes inside< clinit > might not get tracked initially. See the java_crw_demo source and documentation for more info. The injections are based on what the hprof options are requesting |
| is injected The hprof agent can map the two | integers (cnum, mnum) to a method in a class. This is the BCI based "method entry" event. - On return from any method(any return opcode) |
