getFilterExcludingVersionedClasses

public static java.util.List getFilterExcludingVersionedClasses(ClassPathEntry classPathEntry)

Method to return an augmented filter for supported features.

Currently versioned class files (a feature introduced in Java 9) are not fully supported by ProGuard. Only 1 version of a class can be read and processed. If no custom filter targeting a specific version is used, exclude such classes from being read.
