Hi Dima,

may I have a couple of reviews for a quite trivial fix, which splits up the hotspotgc jtreg group: http://cr.openjdk.java.net/~dfazunen/8152422/webrev.00/ https://bugs.openjdk.java.net/browse/JDK-8152422 Looks good. cheers, Per

The purpose of the split is to parallelize the execution of GC tests in JPRT. Running the tests located under the gc/g1 folder takes approximately the same amount of time as running other tests. To reduce the execution time (for ~20%) I propose to remove a couple of slow tests from JPRT run: 38,52 : gc/cms/TestMBeanCMS.java (former name test/gc/6581734/Test6581734.java) CMS is updating vary rare now, so it's very unlikely to break the area under this test 18,05 : gc/survivorAlignment/TestPromotionFromSurvivorToTenuredAfterMinorGC.java There will remain 3 very similar tests for survivor alignment 5,38 : gc/survivorAlignment/TestPromotionFromEdenToTenured.java 6,47 : gc/survivorAlignment/TestAllocationInEden.java 6,78 : gc/survivorAlignment/TestPromotionFromSurvivorToTenuredAfterFullGC.java so dropping this test will not create a gap in testing. I also restored test which were excluded from JPRT execution a year ago: 90,66 : gc/g1/TestGreyReclaimedHumongousObjects.java the test is the slowest one, but after the split it fits the budget. If someone has objections on adding/removing JPRT tests, please speak up.
