> the get() method on LeftTuple throws a null exception under certain circumstances, which are as yet undetermined.
> Here is the Code:
> public InternalFactHandle get(final int index) {
>         LeftTuple entry = this;
>         while ( entry.index != index ) {
>             entry = entry.parent;
>         }
>         return entry.handle;
>     }
> Note that the loop moves to each parent in succession, but never checks for entry != null. If it does get to the end of the chain, it will throw an NPE
