If this happens the nextIndex reference in PrimitiveIterator will not be updated. At this time the PrimitiveEntry will reference the incorrect index and may result in a NPE.\r\n\r\nModifications:\r\n- If KObjectHashMap.remove(int index) moves entries back then PrimitiveIterator should adjust its nextIndex\r\n\r\nResult:\r\nPrimitiveIterator.remove() updates its internal state to reference the new nextIndex and will not NPE.\r\nFixes
