j2sdk is the former name in version 1.4 and it seems that it cannot 
coexist. Troy sent a message about that a couple of weeks ago. This is the 
reason he built a java-1.4.2-sun-compat that uses Java 1.5. It should work 
without reinstalling 1.4 (this is compatible from application point of view 
and should be transparent as long as java alternaives is correctly 
configured).
