jars are created as part of the image build. You should find 
jdk/lib/rt.jar after that phase.

If you don't want to rebuild images (which shouldn't take very long if 
only a couple of jars needs updating) then you can re-build jdk and then 
execute the existing image using a bootclasspath of jdk/classes
