Description
The following JVM TI functions have been deprecated in this release:
IterateOverObjectsReachableFromObject
IterateOverReachableObjects
IterateOverHeap
IterateOverInstancesOfClass
These functions were superseded in JVM TI version 1.2 (Java SE 6) by more powerful and flexible versions. These functions will be changed to return an error in a future release to indicate that they are no longer implemented/supported. The VM flags `-Xlog:jvmti=trace and -XX:TraceJVMTI=<function_name>` can be used to identify any residual usages of these functions, e.g. `-Xlog:jvmti=trace -XX:TraceJVMTI=IterateOverHeap` is one way to get trace output when IterateOverHeap is used.
