One additional comment about the jdeps --help output https://github.com/openjdk/jdk/blob/master/src/jdk.jdeps/share/classes/com/sun/tools/jdeps/resources/jdeps.properties#L139 main.opt.I=\ \ -I\n\ \ --inverse Analyzes the dependences per other given options\n\ \ and then find all artifacts that directly\n\ \ and indirectly depend on the matching nodes.\n\ \ This is equivalent to the inverse of\n\ \ compile-time view analysis and print\n\ \ dependency summary. This option must use\n\ \ with --require, --package or --regex option. Should this be better 'This option must be used . . .' ? And what about a sentence explaining what 'nodes' you are talking about ? Btw is there some trace mode telling me more where exactly the jdeps tool fails in this particular case ? ------------- PR: https://git.openjdk.org/jdk/pull/10300
