Found that for me it's much easy works with jdk1.6 and its features.
Now my java code looks such:
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("js");
engine.put("args", params);
try {
engine.eval(JSON1);
engine.eval(code);
Invocable invocableEngine = (Invocable) engine;
return invocableEngine.invokeFunction("main").toString();
} catch (ScriptException e) {
throw new RuntimeException("Error in JS code", e);
} catch (NoSuchMethodException e) {
throw new RuntimeException("Can't find main method", e);
}
