Too bad, I've read the dlj licence and it seems packaging just rt.jar 
would violate it. So I've tried using gnu-classpath instead and seems to 
work for everything except two packages (which I've solved differently).

The attached eclass patch thus uses gnu-classpath. I've also added a 
JAVA_PKG_WANT_BOOTCLASSPATH variable to pull the needed dep.
gnu-classpath will just need a revbump to register the classes to 
package.env
