Hi,

If it is in world it's there because you put it there. You should be
able to delete things out that you don't want and then run a
--depclean to get rid of the unneeded junk. I go through mine
occasionally because I will invariably emerge something without
--oneshot when I'm trying to get some troublesome package to emerge
properly or whatever.

For the Java stuff I would just try to remove it and see what breaks.

Obviously if you're doing any development then you may have emerged
libs that aren't required by any packages in portage, but they may
still be used by you. If you're asking yourself "How did this get
here?" then you probably don't need them. :)
