Hi Steve, thanks a lot for this fix. I'm forwarding this to core-libs-dev as well, because that's where the review has to take place. The "ppc-aix-port-dev" list is mostly a marker for the port maintainers to get their attention on relevant changes (so cross-posting is fine in this case :) On Thu, Dec 6, 2018 at 4:26 PM Steve Groeger <GROEGES@uk.ibm.com> wrote:
Hi all,
I have been investigating the issue https://bugs.openjdk.java.net/browse/JDK-8211844 raised by Goetz Lindenmaier which is related to the jdk/java/lang/ProcessBuilder/PipelineTest.java JTReg test failing on AIX. Having done some investigation I have a potential fix fore the issue:

Your change looks good and I can sponsor it. Just as a hint for other reviewers I'd like to mention that this change, albeit in a shared Java file, is still AIX-only because it is in the "AIX" case of a switch statement. @Steve: can you please verify, that your change introduces no regression by running the complete jtreg test suite. Thank you and best regards, Volker
I would appreciate any feedback please, and for someone to be a sponsor for this and to contributute it to OpenJDK.
