All Implemented Interfaces:
Resource
public final class MultiReleaseResource extends Object implements Resource
A resource wrapper that loads the versioned entries from META-INF/versions if the resource contains a main attribute named "Multi-Release" in the META-INF/MANIFEST.MF

A multi-release resource is a resource that contains a set of "base" entries and a set of "versioned" entries contained in subdirectories of "META-INF/versions" directory

The versioned entries are partitioned by the major version of the Java release. A versioned entry, with a version n, 8 < n, in the "META-INF/versions/{n}" directory overrides the base entry as well as any entry with a version number i where 8 < i < n
