ebuild doesn't create a config for sun-jdk making java installation broken. It seems that set_java_env() form java eclass isn't called at all, however I'm not an experienced portage developer to be sure.

JAVA_VM_NO_GENERATION1=false fixes the problem.. but that's probably not the best solution
Only 1.3 and 1.4 jdks are supposed to be backward compatible to generation 1 (and that only for the transition period), 1.5 jdks are generation 2 only. So I guess this is INVALID.
This is by design, as described by UncleOwen. See: http://overlays.gentoo.org/proj/java/wiki/Common_Problems#IhaveJava1.5JDKinstalledbutitisntlistedbyjavaconfig1L
