Hi, Please review the following:
webrev: http://cr.openjdk.java.net/~sdrach/8158295/webrev.01/ <http://cr.openjdk.java.net/~sdrach/8158295/webrev.01/> issue: https://bugs.openjdk.java.net/browse/JDK-8158295 <https://bugs.openjdk.java.net/browse/JDK-8158295> This changeset adds a multi-release jar validator to jar tool. After the jar tool builds a multi-release jar, the potential resultant jar file is passed to the validator to assure that the jar file meets the minimal standards of a multi-release jar, in particular that versioned classes have the same api as base classes they override. There are other checks, for example warning if two classes are identical. If the jar file is invalid, it is not kept, so —create will not produce a jar file and —update will keep the input jar file. Thanks Steve
