We have a multirelease .jar that contains different .class files under META-INF/versions (e. g. META-INF/versions/9/org/apache/logging/log4j/util/StackLocator.class). After running proguard in version 7.2.1, the META-INF/versions folder in the obfuscated .jar is empty.
Does proguard support obfuscating classes under META-INF/versions in general?
If yes, how must it be done correctly?
And if not, what would be the way to convert an multirelease.jar into a non-multirelease.jar for a given version?
