The defect has been detected and confirmed in the function IterateOverHeapObjectClosure::do_object() located in the file src/hotspot/share/prims/jvmtiTagMap.cpp with static code analysis. This defect can potentially lead to a null pointer dereference.

The pointer oop o is passed to the constructor of the CallbackWrapper class, where it is dereferenced without a null check.
