New version looks good to me.

Good. It means no 'excluded' tests for the time being.

Fine by me.

No objection, formatting is just a matter of taste.

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.
