I'm not talking about merging a broken port. This is not a new untested
port. It's been in active use for a number of years and has accumulated
bug fixes, and those fixes have a history which extends beyond the OpenJDK
repositories into distro bug databases and IcedTea release notes.

I agree that it makes sense to clean up some of the development commits
where the result wasn't usable. The point in the history I've chosen
seems to be the point where it switched from development to maintenance
mode, receiving backports of fixes from 9 rather than new work, though
I'm open to using a different one if Goetz thinks another is more suitable.

Merging the changes before that correlates with your idea of importing
a working port as one patch. The list of bugs after that retains the
history of the issues that occurred after the initial port and makes
it clear that those issues are resolved in the version of the port
in OpenJDK.

Yes, it is a matter of keeping the repo "reasonably clean", but not so
clean that it is largely devoid of useful information. Hence the split
I suggest.
