Re: [jruby-user] [ANN] JRuby 9.0.0.0.pre2 Released!

Hi Tom,

That's all working much better on our machines now. We can now run
rails migrations and spec without any errors, which is fantastic.

An issue we are having, though, is when compiling some of our code
using jrubyc (using "jrubyc --verbose lib" to compile the lib
directory). The specific error is:

TypeError: failed to coerce org.objectweb.asm.ClassWriter to
org.jruby.org.objectweb.asm.ClassVisitor
  block in compile_files_with_options at
uri:classloader:/META-INF/jruby.home/lib/ruby/stdlib/jruby/compiler.rb:179

                                <top> at ./jrubyc.rb:3


Does anyone have any ideas about what the problem could be here, or
any way I can help better identify the root cause?

Thanks,

Michael
