I've moved all tests, at least all which were in the repo when I created a patch. to me, all of them seem quarantined tests, not excluded.
have I missed some? or do you think some of them should be excluded?

I’d stick w/ quarantined, since we have been using "quarantined” in that meaning for a while, and besides “problematic” is too generic, it’s also a new work, and I’d prefer not to pollute our dictionary w/ another type of failing tests.

> 4) Would you consider to use the same formatting as jdk does:
I’d rather not, having such alignment doesn’t add much value, but costs a lot, because almost each change would modify number of lines around.

ProblemList gives a possibility to remove a test from execution on a specific OS, arch, and since the expectation is to have more quarantined tests than excluded, it was decided to use ProblemList to quarantine and @ignore to exclude, another reason is to have consistent process for hotspot and jdk tests.
