Looking at the other potentially-exception-throwing actions in that DCmd 
and others, I think a simple delete of the assert and change:

  425     vmSymbols::finalizer_histogram_klass(), THREAD);


  425     vmSymbols::finalizer_histogram_klass(), CHECK);

would suffice. Something upstream has to handle potential errors and the 
pending exception in any case.
