This is the text that I was seeing every time my code ran...

Ok yeah I get it, but it doesn't have to be printed every single time. It's enough to include the licence text file.
So this is how I initialise...
private static final Logger logger =
private PrintStream origOut;
private void init() throws NativeHookException
// disable System.out and turn off logging
origOut = System.out;
// register the native hook and all mouse related listeners
// restore System.out
Now when my code starts I don't get any notices and no logging info printed from JNativeHook.
