      Description

      The stackwalk in VM_GetOrSetLocal::doit_prologue() is unsafe and can crash the VM, because it is
      performed in the prologue of the vm operation, i.e. before the safepoint, and access to local
      variables using JVMTI does not require the target thread to be suspended.
