I can confirm that the current EA build 1.9.0-ea-jigsaw-nightly-h3660-20151022-b86 allowed a successful build using maven (with tests) of the OpenGamma test case, which is a step forward from when I last tried it.
When running "java -listmods" I get outpuy including this: java.base@9.0 java.compact1@9.0 java.compact2@9.0 java.compact3@9.0 java.compiler@9.0 java.corba@9.0 But when I look at the JDK source module-info.java file: http://hg.openjdk.java.net/jigsaw/jake/jdk/file/1b632228f7e5/src/java.base/share/classes/module-info.java It does not contain the version number "9.0". Where is the version coming from? It is weird to see the version number so closely associated with the module in -listmods when so much of the mood music of the current Jigsaw work is that the version is "not our problem guv". Stephen
