Re: javap cannot read module-info.class
One working example certainly doesn't prove absence of a bug :)
But yes, I must have gotten my bash aliases wrong, the reported error
is only printed by the Java 8 version of javap, in 9 it works as expected.
One small bit remains:
If I let our compiler emit CONSTANT_Utf8_info for the module name
without a wrapper CONSTANT_Module_info javap does happily accept this.
"java --list-modules" rejects this, though.
other than that: sorry for the noise,

Objet: javap cannot read module-info.class
compile an arbitrary module-info.java and then:
$ javap module-info.class
Error: error while reading constant pool for /tmp/bin/module-info.class:
unexpected tag at #5: 19
From tweaking the Eclipse compiler it seems that javap is expecting a
CONSTANT_Utf8_info,
where according to JVMS 4.7.25 a CONSTANT_Module_info is required.
JVMS and javac agree, so javap is the odd man out.

It would be interesting to see if the runtime can read this, does "java -p /tmp/bin --list-modules" list the module? -Alan
