Geir Magnusson Jr resolved HARMONY-1123.
----------------------------------------

    Resolution: Fixed

r451082

Tested classlib on Ubuntu 6 using J9 vm.  This fix didn't break anything, 

Fixed the problem, at least w/ simple test classes compiled by Sun's javac and then run on both the RI and DRLVM+classlib
