Hi,

Could I have a review for this change, please: Bug: https://bugs.openjdk.java.net/browse/JDK-8148397 Webrev: http://cr.openjdk.java.net/~mchernov/8148397/webrev.00/ TestIHOPParallel.java - stress test for Adaptive IHOP with logging. Test allocates and frees memory in several threads. Executes with enabled logging for IHOP: -Xlog:gc+ihop=debug,gc+ihop+ergo=debug,gc+ergo=debug . Expects for no crashes during working. TestIHOPStatic.java - provokes concurrent cycle initiation with static IHOP during allocation to check that occupancy and threshold (IHOP) are valid and occupancy is greater than threshold. TestIHOPErgo.java - provokes concurrent cycle initiation with static and adaptive IHOP. Checks that occupancy and threshold are valid. Checks that adaptive IHOP prediction is activated during some iterations. Executed on several configurations with nightly VM options.

looks okay.

Thanks, Thomas
