#2 getJavaFileName ignores jdk classes

Consider the following java source file:

import java.io.*;

class Blah {

private OutputStream mOutputStream;

}

If the project also has a class called OutputStream
(which is how I discovered this bug), then calling
GotoJavaFile in emacs will jump to the project's
OutputStream class which is wrong. It should say "No
source for java.io.OutputStream"

External packages are also wrongly ignored.
