Description

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.

SadPanda.java

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);
