WARNING... WARNING... NOT FOR THE FAINT-HEARTED!!

:> cd myrepo/jdk/src/share/classes/org/openjdk/jigsaw
:> javac -d . `find . -name "*.java"`
:> jar -uvf myrepo//build/solaris-i586/lib/modules/jdk.base/8-ea/classes org
   (Or update the image, 
solaris-i586/jdk-module-image/lib/modules/jdk.base/8-ea/classes)

This only works because the classes are currently stored in a zip 
archive. If this changes the above will obviously not work.
