AIUI the situation is more complex than that

maven seems to be moving towards requiring specific core versions for
builds. some  projects i develop require maven 2, some maven 3. i
manage this situation with a set of custom scripts and installations
independent of gentoo. i expect other developers now work in a similar
way. (same goes for jdks.) the gentoo java stuff just gets in my way
now for development.

FWIW one unresolved challenge for linux distributions with the rise of
bytecode languages (such as Java) is that compressed bytecodes are not
binaries in the usual sense (platform dependent machine executable
machine code). i know that it's a hard thing for the linux community
to hear but it's about time that the community acknowledged that these
languages are now mainstream and stop trying to force them into a
inappropriate provisioning model.
