I do not know where this is documented, but the best way to deal with it
is setting the variable JAVA_PREFERRED_PORTS in your '/etc/make.conf'. I.e.
for jdk15. The complete list is
to be found in '/usr/ports/Mk/bsd.java.mk'.

You can run software that was built by older versions, but not vice
versa. That means you can run software that was compiled by 1.4 on 1.5
but not the other way around. Unless you set something like '-target
1.4' when building.
