> The Java code below should return a string "Hello World!". Instead of that it
> returns an empty string and prints "Hello World!" in the console the
> application runs. The problem exists only inside functions; texts printed
> outside functions are redirected properly:
> {code:java}
> javax.script.ScriptEngineManager manager = new ScriptEngineManager();
> javax.script.ScriptEngine engine = manager.getEngineByName("groovy");
> StringWriter stdOut = new StringWriter();
> engine.getContext().setWriter(new PrintWriter(stdOut));
> engine.eval("def myFunction() { print("Hello World!"); }");
> Invocable invoker = (Invocable) engine;
> invoker.invokeFunction("myFunction", new Object[0]);
> return stdOut.getBuffer().toString();
> {code}
