-----------------------------------------------------------------

Looking at the code, it's the dereference of var 'reference' that throws the NPE:

{code}
finally {
  if (!ok) {
      valueReference.set(null);
      reference.release();
  }
}
{code}

Presumably it's in the if (!ok) block because an earlier dereference in the try block also threw an NPE.
