For release notes With UseG1GC specifying -XX:ParallelGCThreads=0 is no longer allowed. Previously with -XX:ParallelGCThreads=0 G1 would execute some tasks using serial code executed by the VM thread. The closest approximation to this behavior is to specify -XX:ParallelGCThreads=1 which will cause parallel tasks to be executed by a single GC worker thread using parallel code.

Cannot find regression test "gc/8000311/Test8000311.java" in JDK 9 WS.

To reproduce run the JTREG regression test http://hg.openjdk.java.net/jdk8u/jdk8u-dev/hotspot/file/6c57a16d0238/test/gc/8000311/Test8000311.java

Most likely this regression is caused by JDK-8017462
