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.

> The preferred Java for the platform should be Semeru Runtimes Open or Certified (both are available for s390x). Semeru Runtimes are available for Java 8, 11, 17, 18 (for Open Edition) and for Java 11 and 17 (Certified Edition). Eclipse Temurin is a raw build of OpenJDK but not as well optimized for the s390x platform, particularly in the areas of startup performance and memory consumption. While available and certified by Eclipse, it is not the preferred option.
