Hi, please review this change to adapt the JarFileSystem::isMultiReleaseJar method to align with the evolved specification in JEP 238
Bug: https://bugs.openjdk.java.net/browse/JDK-8176709 Webrev: http://cr.openjdk.java.net/~redestad/8176709/jdk.01/ This unfortunately adds a qualified export from java.base to jdk.zipfs, but since the jdk.internal.util.jar package was already exported to three other modules I think it's a low cost option that is preferable to other alternatives such as maintaining separate implementations. Thanks! /Claes
