I'm assuming USE_JAVA only controls RUN_DEPENDS for the port.
Some java ports don't need any jdk to build them like tomcat. Others like
eclipse will require a specific version so that the package maintains
compatibility with it. Meaning eclipse should be built with 1.4 and only 1.4
so that the package maintains compatibility with 1.4 when 1.5 is available
to use with it too (unless we want to get into using -target 1.4).
There is another issue related to this that I haven't a solution for right
now. By way of example, when tomcat is installed it would be great if it
could find out which jdk satisfied the run depend, so that JAVA_HOME
could be defaulted correctly in /etc/tomcat/tomcat.rc. A while back I tried
to hack the pkg/INSTALL script to figure this out, but didn't find a solution.
Right now this is a post install step. Other java ports will have this issue
too. Is that something that can be done now, or will it require some
enhancement of pkg tools?
