title: How to attach source of com.sun.script.javascript for debugging RhinoScriptEngine in Eclipse
body: <p>I would like to debug RhinoScriptEngine in com.sun.script.javascript package.
  to see the source code i attach the openJDK openjdk-6-src-b25-01_may_2012.
  but when i try to step into any method of e.g. RhinoScriptEngine or ScriptEngineManager it doesn't work...
  eclipse opens the corresponding class, but the debugger doesn't step through the source code</p>
  
  <p>how to fix this and debug RhinoScriptEngine and Rhino itself?</p>
