javap cannot read module-info.class

[Remi Forax]

Hi Stephan,
there is something wrong from your side, it works for me :)

/usr/jdk/jdk-9-b175/bin/javap --module-path target/main/exploded/ --module fr.umlv.asm.test module-info
Compiled from "module-info.java"
module fr.umlv.asm.test {
  requires java.base;
  requires org.objectweb.asm.all.debug;
  exports fr.umlv.asm.test;
}

/usr/jdk/jdk-9-b175/bin/javap -m java.base module-info
Compiled from "module-info.java"
module java.base at 9 {
  exports sun.reflect.generics.reflectiveObjects to
    java.desktop;
  exports java.util;
  exports java.lang.ref;
  exports jdk.internal.misc to
    java.rmi,
    java.sql,
    jdk.jshell,
...

cheers,
Rémi
