The code to reproduce (using embedded groovy)
//call groovy expressions from Java code
Binding binding = new Binding() {

public Object getVariable(String key) {
if (key.equals("lValue"))

{ return new Long(60); }

if (key.equals("rValue"))

{ return "4.0"; }

return super.getVariable(key);
}
};

GroovyShell shell = new GroovyShell(binding);
String expr = "println lValue; println rValue; println lValue > rValue; return lValue+rValue";

Object value = shell.evaluate(expr);
System.out.println(value);
