        One of the profiler vendors reports a crash when they enable the jvmtiStringPrimitiveCallback implementation. From the description it appears that the heap iteration (IterateThroughHeap) encounters a partially constructed java.lang.String. That is, the value field is null. The invoke_string_value_callback function doesn't check for this case and so will crash.
