How to test OpenJDK?

There is no reason why it should not be possible to have 100% pass rate
for most of the jdk tests as well. If there are problematic tests in
test suite, we should identify those tests, and then logically
tests into two groups -- those that should always be expected to pass,
those that don't, for whatever reason. That at least would allow to to
a quality bar for any OpenJDK build of which tests should always pass.
Frankly, I've never understood the attitude that it is OK to have
fail, and which don't deserve attention, but as long as we have such
we should identify them, using any of the available jtreg mechanisms,
such as keywords, @ignore, or exclude lists.
And, all the other, unmarked tests, should always pass, all the time,
if a test starts failing after you've changed code, you should assume
broken something and it deserves attention.
If necessary, we could/should have separate Makefile rules for testing
two different groups of tests, so that we have an obvious 100% pass
the tests in the main group of good tests.
