Remove gcj+gij warning about unneeded import java.lang.*;.  This warning is consistent with remarks made in http://jas.freehep.org/Documentation/UsersGuide/java.htm about how java.lang is always implicitly imported.  Indeed, removing the import got rid of the warning, but other java compilers might not like that so I replaced import java.lang.*; with the explicit pair, import java.lang.Math; and import java.lang.Integer; which also got rid of the warning.
