>Description:
it would be nice to have a note in UPDATING on how to rebuild an installed
java/jdk* under >= 8. since java/jdk1* requires an installed java environment
in order to build it fails due to the version bump of /lib/libz.so.4 to
/lib/libz.so.5.

to be able to rebuild any installed java/jdk* one needs to do the following:
`echo libz.so.4 libz.so.5 > /etc/libmap.conf` in order for any java/jdk* port to update.

i haven't checked what the situation is like when no java environment is
installed, but i believe this doesn't cause a problem since java/diablo-jdk*
is used for bootrapping then.
