It seems the [brew formula for mvnd](https://github.com/mvndaemon/homebrew-mvnd) was updated to `0.8.2`. Oddly, however, I'm still receiving the same exception as [before](https://github.com/apache/maven-mvnd/issues/337#issuecomment-1270296072) after installing the updated version. ```shell ❯ brew list mvnd ─╯ /opt/homebrew/Cellar/mvnd/0.8.2/bin/mvnd /opt/homebrew/Cellar/mvnd/0.8.2/bin/mvnd-bash-completion.bash /opt/homebrew/Cellar/mvnd/0.8.2/libexec/bin/ (2 files) /opt/homebrew/Cellar/mvnd/0.8.2/libexec/conf/ (3 files) /opt/homebrew/Cellar/mvnd/0.8.2/libexec/mvn/ (85 files) ``` Against the Temurin 8 JDK: ```shell ❯ mvnd --version ─╯ Error: A JNI error has occurred, please check your installation and try again Exception in thread "main" java.lang.UnsupportedClassVersionError: org/mvndaemon/mvnd/client/DefaultClient has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:756) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:473) at java.net.URLClassLoader.access$100(URLClassLoader.java:74) at java.net.URLClassLoader$1.run(URLClassLoader.java:369) at java.net.URLClassLoader$1.run(URLClassLoader.java:363) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:362) at java.lang.ClassLoader.loadClass(ClassLoader.java:418) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:352) at java.lang.ClassLoader.loadClass(ClassLoader.java:351) at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:601) ``` I decided to downloaded version 0.8.2 again and test as per @gnodet [here](https://github.com/apache/maven-mvnd/issues/337#issuecomment-1271448699) and this version works fine against the same Java 8 source that failed above. I'm not yet sure what's going on but thought I'd post it here before I investigate. -- This is an automated message from the Apache Git Service.
