Not really. It is C code and just a static function in a file. To reuse it we would have to expose it as an API in the global namespace. It is only two lines.

`JavaThread::current()` - at least I assume we always have a `JavaThread`. If not then we would need to use:

Thread* current = Thread::current();
if (current->is_Java_thread()) {
  JavaThread::cast(current)->print_jni_stack();
}
