I agree that #1 is the cleanest, easiest technical approach.  The
difficulty is convincing an attorney that a file in Harmony Class Lib
called "blah blah GNU blah blah CLASSPATH" has nothing to do with gnu
or classpath.  I vote for adding a few lines of code to avoid spending
hours with an attorney.   How about an algorithm that first checks for
gnu.classpath.PointerXX and if its not found then looks for
xxx.yyy.zzz.Pointer class?   I am not happy with putting Pointer
classes in the java.lang package.  Maybe create a new package called
kernel_path.  Thoughts?

This is an excellent idea!  I really like it.
