Good Morning, As documented in much detail in the following ticket, 21.0.7 broke Aarch64 support on the Cortex A53 CPU.
https://github.com/adoptium/adoptium-support/issues/1295 There is a reproducer in the Ticket, basically the steps are: * Setup Ubuntu cloud image on qemu-system-aarch64, and use a Cortex A53 CPU * Download and use Java 21.0.7+6 - I tried Temurin, Microsoft and Azul. All misbehave. * "Using" means e.g. running ./gradlew tasks on any freshly downloaded repo, e.g. the gradle sample repo. * ... or running any more complex java program, which immediately exhibits strange behavior like these: * java.security.ProviderException: Cannot find aliases for HmacSHA512 * Note: It is not a specific algorithm which is not found, it just randomly fails on very different ones. * java.lang.IllegalArgumentException: java.lang.ClassFormatError: Duplicate method name "toString" with signature "()Ljava.lang.String;" in class file jdk/proxy2/$Proxy3 * Exception in thread "main" java.lang.annotation.IncompleteAnnotationException: java.lang.annotation.Retention missing element value * ... and even more ... * Another note: of course the very same binaries run without any issue on other CPUs, like the A57 for instance. I first thought that this is an issue with my actual A53 hardware I have here. However since this behavior is the same also on an emulated A53 in QEMU: here I am reporting 🙂 Versions before 21.0.7(+?) do not expose these problems. I can run any program just fine on 21.0.6+7 and older. The GitHub issue has a lot of information already present, but I can provide more on demand - both from an emulator as well as the real hardware. Any help would be greatly appreciated - even if it is a statement that A53 is no longer supported (which would be a bummer, we have a lot of hardware with those CPUs).
