The spec for j.u.Collections
http://docs.oracle.com/javase/8/docs/api/java/util/Collections.html
says:

"The methods of this class all throw a NullPointerException if the collections or class objects provided to them are null."

However the following call won't lead to NPE

 java.util.Collections.asLifoQueue((Deque) null)

The following JCK9 test would fail due to this:
