hi dear community,

got stuck with a problem, when I create a new instance of Asciidoctor, I'm getting this nice exception:

Exception in thread "main" java.lang.IncompatibleClassChangeError: Found interface org.objectweb.asm.FieldVisitor, but class was expected

Quick check shows that jruby-complete-1.7.16.1.jar!/org/objectweb/asm/FieldVisitor.class is an abstract class as the Jruby code expects, however, my classpath contains a reference to asm 3.1 where FieldVisitor is actually interface :)

Has anyone had similar issue before?
