Description
Currently the heap functions in JVMTI do not allow an agent to access the primitive or primitive array fields of an object. When doing memory analysis a primitive can't keep an object alive but it may be useful to see the char[] value of a string.

In addition it would be desirable to be able to determine an array length during the iteration - this is important if a profiler doesn't instrument the array allocation site (newarray bytecode) and is tagging objects as they are encountered during the iteration.
Comments
EVALUATION The implementation has been completed and should be integrated for b51 or b52.
