Description

I'm trying to compile a Ruby script to Java source using jrubyc.
The compilation fails and i'd like to be able to identify the piece of script code that causes the compiler to fail.
The compiler error message doesn't currently provide enough information for identifying the erroneous line from the compiler
error output.

jrubyc --verbose --java ruby

Failure during compilation of file src/main/ruby/foo.rb:

Marko, Can you provide the signature which is causing this problem? You can put a print in /opt/jruby-1.6.7/lib/ruby/site_ruby/shared/jruby/compiler/java_class.rb right before line 142. The last signature to print will be the signature we cannot compile. As a bonus of providing this information, I will try and make a better error message.

here's the output from ClassNodeWalker.build_signature:

**SIG: Object receive_push()
**SIG: Object deliver_message(Object to,Object cc,Object subject,Object content)
**SIG: Object configure_delivery(Object config)
**SIG: Object configure_mail_defaults()
**SIG: Object mail_configured?()

so i take it that mail_configured is the offending method.
the method is declared like this:

def mail_configured?

Reproduced with a trivial case:

class Foo
  def blah?; end
end

I would imagine we're allowing the ? to get through and that's confounding the Java signature parser. A workaround:

class Foo
  java_signature 'boolean isBlah()'
  def blah?; end
end

The JavaSignatureParser should provide a better error, though.
