Follower of OpenJ9 for OpenJDK 17
by Sarah Julia Kriesch 16 Jun '22

Hello together, Thank you to Fridich for providing us the OpenJDK 17 in openSUSE Tumbleweed. That is running nice. But we have got an open question, because we can not identify it in the spec file: @Fridrich Which JVM is used there/ have you chosen? Then we have provided OpenJDK 11 also based on OpenJ9. We have figured out, that it does not exist any more. There are 2 new options now for OpenJDK 17: 1) OpenJDK 17 based on the Semeru Runtimes [0] 2) OpenJDK 17 based on Eclipse Temurin [1] There was a discussion about this JDK topic on the general s390x mailing list [2] in March. Christian gave this feedback by IBM Java Developers: "Note that since July 2021, the OpenJDK+OpenJ9 builds at AdoptOpenJDK .net have been built by IBM using the same components and re-branded under the IBM Semeru Runtimes name. For the Eclipse Adoptium API going forward, they will only "promote" certified builds, ie. IBM Semeru Runtimes Certified Edition. The Eclipse Adoptium Marketplace is still being worked on. IBM has also done a "soft launch" on our own fork of their API which serves IBM Semeru Runtimes, both Certified Edition and Open Edition, which we host. We hope to have an announcement on that shortly. The code is the same so you can use ALMOST the same query and just swap out the base of the URL and the Vendor. Instead of vendor adoptopenjdk use ibm for Open Edition and ibm_ce for Certified Edition." It seems, that the Eclipse Adoption is only "certified by Eclipse" (if I understand it correctly). We need feedback by @IBM in this case, for future Java support in openSUSE and SLE. I know, that we have got some people on our mailing list. :) @IBM The general OpenJDK 17 is running (stable) on openSUSE Tumbleweed. Do you prefer the general OpenJDK 17, Eclipse Temurin or the Semeru Runtimes in our releases? We are open to compare one of them with the general OpenJDK 17 and that we can support your preferred OpenJDK 17 in SLE/openSUSE Leap and openSUSE Tumbleweed the same as we have done with OpenJDK 8 and 11 based on OpenJ9.

Hello together, tomorrow is the next of our training/meeting sessions. I am open for questions and a round to find together solutions for open tasks. Therefore, you can suggest any interesting topic for you. We will meet us at 18:00 (German time)/ 9:00 (Pacific time)/ 17:00 (Nigeria) / 13:00 (Brazil) on our openSUSE Jitsy: https://meet.opensuse.org/s390x Topics for this session: 1) Status updates 2) OpenJDK 17 (can it be used as a default) 3) Participation at the Open Source Day (orga/planning) 4) BBQ party at the end of June (in the garden) 5) Open topics 6) Q&A (open for questions for people missing in last sessions) I was at the IBM z16 Symposium and will tell a little bit about my experience there.

openSUSE @ Open Source Day (Mentoring)
by Sarah Julia Kriesch 09 Jun '22

09 Jun '22

Hello together, last year was the first time, that I and my zsystems team has participated at th virtual Open Source Day [0]. The Open Source Day is a hackathon day in the USA, where female mentees can contribute to open source projects. I was asked because they had looked for a Linux community and a female community Representative. I can say, that we had success and have received also some new openSUSE Members on this way. But we had provided only s390x tasks. We want to join again. Is anybody else interested to join our team as a Mentor? Then we can provide more tasks (outside of s390x). These tasks can be also packaging related or other (development) stuff. But most should be entry level. The next Open Source Day is Friday, September 16th, 2022. A small warning for all openSUSE Contributors from Europe: That will be a hack night for us! ;) We (from the zsystems team) are planning to join this event again. We would be happy about additional openSUSE Mentors, because the former assigned Mentors were more on an intern level as a qualification. In parallel, a female Release Manager by a hardware distributor should have been a Mentee and interacted as a Mentor. If you are interested to join us, answer to this email and apply on the Open Source Day page[1] as a Mentor. Best regards, Sarah [0] https://opensourceday.anitab.org/agenda/session/570707 [1] https://ghc.anitab.org/programs-and-awards/open-source-day/

Call for testing of OpenJDK 17
by Sarah Julia Kriesch 06 Jun '22

06 Jun '22

Hello together, it was nice to meet you all at the openSUSE Conference. :) We had nice talks and we have got news for our ZSystems port. Fridrich has fixed all the former maven issues related to s390x and has built OpenJDK 17 for us. We are allowed to test this Java version. If all is working fine, we can make it the default Java in openSUSE Tumbleweed. Thanks for this effort to Fridrich! We will test it and speak about the result in our next meeting. Best regards, Sarah

Next meeting at the pre-conference party of the openSUSE conference (Kater Murr)
by Sarah Julia Kriesch 29 May '22

29 May '22

Hello together, our next meeting is during the pre-conference party of the openSUSE Conference. Therefore, I want to invite you all (interested people) for next Wednesday at 18:00 to the Kater Murr in Nuremberg. :) I have got also a present for all, who are supporting the s390x port and have been supporting me via the Release Engineering Team. I will provide you free drinks as I promised it already last year. That is the first time to meet you all in presence. The budget for the drinks will come from the double salary (IBM + Accenture) about 4 months in the last year. The money from IBM is invested in the correct place with that. Best regards, Sarah
