Well, that's exactly the issue that the new Java handling should solve
(compile time JVM version switching). In your previous post you've said
that you have problems setting the generation-1 system VM. I suspect that
there's something wrong with your setup, even though you might have
followed the instructions closely...

Maybe you could post the output of the following commands?

# java-config-1 -L
# java-config-2 -L
# which java
# java -version
# echo ${PATH}
# emerge -pv =sun-jdk-1.4*
# emerge -pv =sun-jdk-1.5*
# emerge --info

That would clear the situation a bit.
