Not if it wants to be consistent with
http://download.oracle.com/javase/6/docs/api/
don't'cha think?

And the so-called "hierarchy" of java.util and java.lang is that they are 
equal.  The language reserves for itself the entire panoply of java.* and 
javax.* packages.

backward compatibility.  And why should it?  java.lang and java.util are 
equal.  The language reserves for itself the entire panoply of java.* and 
javax.* packages.
