Hi all, hi Jon,
while updating ASM6 to the new classfile format, i think i've found a bug in 
javap.

javap as no trouble to read module-info.class if the class is specified directly
$ /usr/jdk/jdk-9-jigsaw/bin/javap module-info.class
open module com.google.guava {
   requires java.base;
   requires java.logging;
   requires java.annotations.common;
   requires jdk.unsupported;
   exports com.google.common.io;
   ...
}

but if the module-info.class is in a (modular) jar,
/usr/jdk/jdk-9-jigsaw/bin/javap --module-path deps -m com.google.guava 
module-info
Error: error while reading constant pool for module-info: invalid index #0

I've created JDK-8170708 to track this.
