Hi all,

can I have reviews for this small change to the TestVerifyGCType test to make it stable? The problem has been that due to different number of threads used, different amount of heap waste has been "produced", only randomly triggering the expected mixed gcs. By fixing the number of threads used and decreasing G1HeapWastePercent the mixed gcs can be forced reproducably. CR: https://bugs.openjdk.java.net/browse/JDK-8193067 Webrev: http://cr.openjdk.java.net/~tschatzl/8193067/webrev/ Looks good, thanks for fixing this Thomas!

Thanks, Stefan

Testing: failing test passing multiple times in CI Thanks, Thomas
