Hi, this has nothing to do with the minimum Java version in your Java built, it only has to do with the runtime Java version. If you use Java 19 or later, the classloader needs to be able to find the version specific support classes for MemorySegment (foreign API) and Vector API in the JAR file, which it clearly says: Caused by: java.lang.ExceptionInInitializerError: Exception java.lang.LinkageError: MemorySegmentIndexInputProvider is missing in Lucene JAR file [in thread "main"] Lucene's JAR files are modularized (https://openjdk.org/jeps/261) MR-JAR (https://openjdk.org/jeps/238) files with service provider (SPI, https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/util/ServiceLoader.html). If you want to merge different JAR files and Lucene's JAR files are part of it, please read ALL the three specs above and then ensure the following: - All files in `META-INF/services` _with same name need to be merged together_ and placed in resulting JAR (https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/util/ServiceLoader.html) - All files in `META-INF/versions` need to be copied to resulting JAR with exactly same directory structure. Those files are the version specific classes and are only loaded depending on the Runtime JDK (https://openjdk.org/jeps/238). - META-INF/MANIFEST.MF must contain `Multi-Release: true` (https://openjdk.org/jeps/238). - All class files named `module-info.class` should be removed as the resulting JAR file is no longer modularized. Keeping them inside may fail to load the application in modularized runtime (https://openjdk.org/jeps/261). -- This is an automated message from the Apache Git Service.
