What is the correct syntax for this in jruby 1.6.8?

I am trying to make use of this file with the jruby-jars 1.6.8

hck/open_nlp/blob/master/lib/open_nlp/parser/parse.rb

module OpenNlp
  class Parser::Parse
    include JavaClass

    attr_reader :j_instance

    self.java_class = Java::opennlp.tools.parser.Parse

    # Initializes instance of Parser::Parse
    #
    # @param [Java::opennlp.tools.parser.Parse] java_instance
    def initialize(java_instance)
      java_instance.is_a?(self.class.java_class) ||
        raise(ArgumentError, "java_instance must be an instance of #{self.class.java_class.name}")

      @j_instance = java_instance
    end

    # Composes tree bank string, nested string representation of sentence parts, parts-of-speech and words,
    # for example:

This file has been truncated. show original

but I would get syntax error around line 45 of the above file

The following is the error that I would get. What is the correct syntax
for jruby 1.6.8? I know that this file works in jruby 1.7.0 (jruby-jars
1.7.0 http://rubygems.org/gems/jruby-jars)

1.6.8 defaults to ruby 1.8.7, whilst 1.7.0 default to ruby 1.9.3.
The syntax you are using is 1.9-specific, so try:

data = { :type => kid.getType, :parent_type => self.j_instance.getType,
:token => kid.toString }

…or she can start JRuby version (< 1.7) with the --1.9 option, no?..

…by putting “–1.9” in the JRUBY_OPTS environment variable, or
specifying “–1.9” on a JRuby command line?
