> The following code snippet throws a NPE on a fairly recent version of 1.5. I would expect
it to return true, or at the very least, to throw a meaningful exception.
> {code:title=SadPanda.java|borderStyle=solid}
> VisibilityEvaluator evaluator = new VisibilityEvaluator(new Authorizations("a".getBytes()));
> ColumnVisibility cv = new ColumnVisibility(new byte[0]);
> //The following line throws a NPE
> boolean result = evaluator.evaluate(cv);
> {code}
