I'm trying to use JRuby 1.7.4 within a Java webapp. Here's the code I'm trying to run:

require 'strscan'
scanner = StringScanner.new("test\ntest\n")
scanner.bol?

this is being executed using the following Java code:

    ScriptEngineManager manager = new ScriptEngineManager();
    ScriptEngine engine = manager.getEngineByName("jruby");
    InputStream resourceAsStream = Thread.currentThread().getContextClassLoader().getResourceAsStream("test.rb");
    InputStreamReader inputStreamReader = new InputStreamReader(resourceAsStream, Charset.forName("UTF-8"));
    engine.eval(inputStreamReader);

Unfortunately it ends up with this exception:

NoMethodError: undefined method `bol?' for nil:NilClass
  (root) at <script>:3

javax.script.ScriptException: org.jruby.embed.EvalFailedException: (NoMethodError) undefined method `bol?' for nil:NilClass
    at org.jruby.embed.jsr223.JRubyEngine.wrapException(JRubyEngine.java:104)
    at org.jruby.embed.jsr223.JRubyEngine.eval(JRubyEngine.java:121)
    at org.jruby.embed.jsr223.JRubyEngine.eval(JRubyEngine.java:146)

Any idea what could be wrong?

Solution was quite hard to find, it seems to be linked to Intellij Idea which adds the following path in the classpath which makes the test failed:

C:\Users\theaterofthought\.IntelliJIdea12\config\plugins\ruby\rubystubs\rubystubs18

Clearing and recreating the IDEA project helped to get a new launcher for my test working without this path in the -classpath argument.
