JDK Ports don't conflict. None of them. And because many Java developers
have several JDKs installed, noone will ever put a CONFLICT line into
JDK port.

The only way to resolve this is to detect weather a dependency is required
in the same way as a port does.

I suggest to check for the existence of the file and when the file is
from a different port, 'pkg_info -W' should be called and whatever turns
out to be the origin, should be entered as a dependency in /var/db/pkg.
