Hi all,

could you please review this clean up of some hotspot tests? these tests are inapplicable in some of configurations, in some cases this can be expressed by @requiers, in others it can not be due to a dynamic nature. the latter cases are addressed by using new functionality added to jtreg 4.2 b13[1] -- throwing jtreg.SkippedException exception, which is known by jtreg and if jtreg catches this exception from a test, the test's will be marked as skipped.

testing: hotspot tests

Thanks,
