OTOH after some thought, this error simply means that while currently
you have 1.4 system JVM, some libraries were compiled with 1.5 JVM.
This is unfortunate, because Java 1.4 cannot use 1.5 classes (their
internal file format is different).

Maybe you should look into java-1.5-fixer, previously posted by Joshua
on the same list? (http://article.gmane.org/gmane.linux.gentoo.java/839)

It's also possible to rebuild the offending packages by hand, but you
will have to find them manually (it may take some time, though...)
The first step is to determine the packages that depends on Java and
then remerge them. I've done it once, so I know it's at least possible :)

# emerge -avu gentoolkit    ### If you don't have equery, that is
# equery depends virtual/jdk | tee ~/java-packages.txt | less

HTH,
Wiktor
