I did look through some of the failures and it looks we basically need
just 3 hosts:
HOST = "javaweb.sfbay.sun.com";
REFUSING_HOST = "jano.sfbay.sun.com";
FAR_HOST = "theclub.ireland.sun.com";
UNRESOLVABLE_HOST = "blah-blah.blah-blah.blah";
With daytime and echo available. The only wrinkle is that some tests
expect to be able to use quick timeouts from HOST, but to need long
timeouts from FAR_HOST. I think we could provide something public for
this. But I might have missed some tests that need other services. Do
you have a full overview?

It depends on the version and the distribution. IcedTea6 now calls
itself OpenJDK, but IcedTea7 calls itself IcedTea. Ubuntu has a patch to
return "Java(TM)" here. And we might actually might want to make that
the default. There are already bug reports about applications and
applets testing for this string to be exactly in the way as the
proprietary implementations (you could argue that is a bug in that
application/applet, but users don't really care unfortunately).
Whenever possible I think we should make this configurable on a specific
test property. That is more work, but allows all derivatives, not just
Sun's ClosedJDK to use the same tests with their own settings. The
defaults should of course be what works with generic upstream OpenJDK.
I was looking at this particular test and I didn't immediately see why
javax.crypto.SunJCE_x couldn't be replaced with a commonly available
class in OpenJDK. What is special about those classes that they need to
be explicitly tested against?

What do you precisely mean when you say that you have an "if production
JDK"? What functional feature does that test against?
