As some of you noticed, last night I was able to build and run Forge with the latest early access build of Open JDK 9 (from the Jigsaw forest!). I had to do just one manual workaround. I had to manually add the following dependency to the javaee/impl/pom.xml and shell/impl/pom.xml:

      <dependency>
         <groupId>org.jboss.forge.furnace.container</groupId>
         <artifactId>simple-api</artifactId>
         <scope>provided</scope>
      </dependency>

It was a problem that was already found and documented in this JIRA:

The JIRA says that this problem occurs with Java 8, build 20. So my question is whether this is fixed in later builds of Java 8. If yes, I will report this to the Open JDK folks to up-port the fix to Java 9 as well. If not, I guess we should fix the poms of the respective projects?

Thanks,

Ivan

P.S. Sorry for the 'lazy web' style of message. I know I could have run the build with newer Java 8 by myself :)

P.P.S. Thanks to Mani Sarkar from LJC that went the hard way last week and found this workaround for me
