Hi, I'd like to upgrade the JOpt Simple library we are using to version 5.0.4. Bug: https://bugs.openjdk.java.net/browse/JDK-8203891 Complete webrev: http://cr.openjdk.java.net/~jlahoda/8203891/webrev.00/complete/ Delta webrev only showing (all) JDK changes in JOpt Simple and related changes in tests needed for the upgrade, etc.: http://cr.openjdk.java.net/~jlahoda/8203891/webrev.00/joptsimple.delta/ Probably the biggest issue with this upgrade is that for two subsequent parameters: "--libs=", "/tmp" "/tmp" used to be interpreted as the parameter of "libs", but now the "libs" parameter is empty (as there's nothing behind the '='). See the changes to test/jdk/tools/jmod/JmodTest.java for an example. Hopefully, this is a reasonable change. How does this look? Thanks, Jan
