Description

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:

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();
