Open ppc/s390/aix issues
by Lindenmaier, Goetz 09 Jan '19

09 Jan '19

Hi, We are now working on the ppc/s390/aix ports for quite some years. With the release of jdk11 we delivered a very comprehensive and well maintained port I think. For example, the jdk and hotspot jtreg tests can be run quite stable on these platforms. I filed bugs for all the remaining issues we see, at least in the test setup we run at SAP. Everybody is invited to join in and fix these few finally :) 8207404: MulticastSocket tests failing on Aix https://bugs.openjdk.java.net/browse/JDK-8207404 8030957: AIX: Implement OperatingSystemMXBean.getSystemCpuLoad() and .getProcessCpuLoad() on AIX https://bugs.openjdk.java.net/browse/JDK-8030957 8211769: Port Dtrace support to ppc. https://bugs.openjdk.java.net/browse/JDK-8211769 8211771: Port Dtrace support to s390x. https://bugs.openjdk.java.net/browse/JDK-8211771 8211767: jtreg: Some SA tests are failing on PPC64 https://bugs.openjdk.java.net/browse/JDK-8211767 8211844: [aix] ProcessBuilder: Piping between created processes does not work. https://bugs.openjdk.java.net/browse/JDK-8211844 8211847: [aix] java/lang/ProcessHandle/InfoTest.java fails: "reported cputime less than expected" https://bugs.openjdk.java.net/browse/JDK-8211847 8211854: [aix] java/net/ServerSocket/AcceptInheritHandle.java fais: read times out https://bugs.openjdk.java.net/browse/JDK-8211854 8211851: /java/nio/channels/AsynchronousSocketChannel/StressLoopback.java times out (aix) https://bugs.openjdk.java.net/browse/JDK-8211851 8211841: [aix] sun/nio/cs/OLD/TestIBMDB.java fails with compilation error https://bugs.openjdk.java.net/browse/JDK-8211841 Best regards, Goetz.

RFR(S): 8213436: Obsolete UseMembar
by Mikael Vidstedt 08 Nov '18

08 Nov '18

Please review this change which obsoletes the UseMembar flag and removes the code that then becomes unreachable/dead. bug: https://bugs.openjdk.java.net/browse/JDK-8213436 <https://bugs.openjdk.java.net/browse/JDK-8213436> webrev: http://cr.openjdk.java.net/~mikael/webrevs/8213436/webrev.00/open/webrev/ <http://cr.openjdk.java.net/~mikael/webrevs/8213436/webrev.00/open/webrev/> * Background (from jbs) The UseMembar flag was deprecated in JDK 10, and is default true/enabled on all platforms since that same release. It should be obsoleted and the then dead serialization page functionality it controls should be removed. * Testing tier1. If anybody wants to take it for a spin on aarch64/ppc/s390/x86_32 that wouldn’t hurt. (Unrelated to this change: It would be really nice to clean up some of the (mostly) duplicated code in the os/signal handling area...) Cheers, Mikael
