ewarn/enotice tells me: Package: blackdown-jdk-1.4.2.03-r2 * It appears you are removing your default system VM! * Please run java-config -L then java-config-S to set a new system VM! but java-config-S doesnt exists. I think it's missing a space and argument: "java-config -S <n>"
It was in eclass/java.eclass, not in blackdown-jdk. Thanks, fixed.
