Hello,

My name is Guillaume and I'm working on Asciidoctor.js[1]
We are testing Asciidoctor.js against the latest JDK9
http://download.java.net/jdk9/archive/b42/binaries/jdk-9-ea-bin-b42-linux-x64-10_dec_2014.tar.gz

We have a simple jjs script that load the Asciidoctor.js file:

load("./dist/asciidoctor-all.js");

var data = "= asciidoctor.js, AsciiDoc in JavaScript\n" +
"Doc Writer <docwriter at example.com>\n\n" +
"Asciidoctor and Opal come together to bring\n" +
"http://asciidoc.org[AsciiDoc] to the browser!.\n\n" +
"== Technologies\n\n" +
"* AsciiDoc\n" +
"* Asciidoctor\n" +
"* Opal\n\n" +
"NOTE: That's all she wrote!!!\n\n" +
"include::spec/share/include.adoc[]";

var options = Opal.hash2(['safe', 'attributes'], {'safe': 'server',
attributes: ['showtitle']});
var html = Opal.Asciidoctor.$convert(data, options);
print(html);

The asciidoctor-all.js is generated from Ruby using Opal[1] so the code is
a bit hard to read but you can view the source here[2].
Here is the error thrown by Nashorn:

./dist/asciidoctor-all.js:24407 TypeError: java.lang.VerifyError: Bad local

Note that the same code is working with the latest JDK8.

Thanks,
