I have done some work to make jclouds compatible with Java 9: https://issues.apache.org/jira/browse/JCLOUDS-1101
It appears that jclouds 2.0.2 mostly works with Java 9 although users must add --add-modules java.xml.bind to their java invocations. Testing jclouds itself with Java 9 requires jumping through additional hoops: https://issues.apache.org/jira/browse/JCLOUDS-1101?focusedCommentId=16146769#comment-16146769 It would be nice to do more testing before 2.1.0 release. -- Andrew Gaul http://gaul.org/
