Description

Removing the final element(s) in a MultiSet doesn't set the count on a MultiSet.Entry to zero.

protected int getCountAfterRemoval(MultiSet<String> multiset) {
  MultiSet.Entry<String> entry = multiset.entrySet().iterator().next();
  entry.getCount(); // = 2
  multiset.remove(entry.getElement());
  entry.getCount(); // = 1
  multiset.remove(entry.getElement());
  return entry.getCount(); // Still = 1, should be 0
}
