As I've said elsewhere, but for the public record I will repeat,
whatever mechanism we use anyone writing regression tests has to start
thinking about what dependencies their test has. Then they have to
record those dependencies somewhere. While tagging a single test in the
future seems fine, it is not fine to have to tag a few thousand tests
initially. Conversely having to potentially edit one line in the groups
file hardly seems burdensome.
But perhaps down the track we can use the group definitions as input to
a tool that will auto-tag the tests - if/when a complete tagging scheme
As for the move to modules ... I think that is a whole new ball game.

Tooling/automation would of course be good, I just don't see the pieces
in place as yet.

Yes. As noted in the file the dependencies are not only what is being
tested but what test infrastructure is being used. The testng tests uses
xml which restricts them to compact2. Some tests use jps/jcmd or
tools.jar which restricts them to a full jdk.

That is up to the nio-dev folk but I certainly wouldn't object! I was
contemplating simply adding sun/nio/cs to needs_charsets, which would
artificially restrict some of those tests, but simplify the expression.
There are 67 tests, of which 41 actually need charsets.jar.

Thanks! - that's a simple oversight on my part. Fixed.
Thanks for the review.
