>            Assignee: Carsten Ziegeler

> The RhinoJavaScriptEngine does not preserve it scope, so that the scope is reset between each call to eval().
> So that:
> RhinoJavaScriptEngineFactory factory = new RhinoJavaScriptEngineFactory();
> ScriptEngine engine = factory.getScriptEngine();
> engine.eval("var f = 1");
> engine.eval("f += 1");
> ... fails with a "ReferenceError: "f" is not defined"
> The problem seems to be that "scope" is a local variable in RhinoJavaScriptEngine.eval(), while it should have been a class field. 
> I have prepared a patch and a test (coming up), but I'm not familiar with the script engine code, so the fix might very likely break other stuff.
> So please review this.
