There are however much better ways to debug your code, namely the debugger.

Agreed, Learn to use break points (The red dots). If you have a watchdog on turn it off so the server won't kill itself if you're longer then a minute in debug. If you haven't make sure you grab the sources on the forge download which iirc is a mod template, when that's all in your IDE and you set up the de-obfuscated environment etc. You can generate the runs, run either the server or client in debug will enable the server to halt on break points, which can be set during runtime. Additionally, this will allow you to reload classes - This will let you change the internal logic of any existing method. 

 

You will be able to see full details of objects in memory while in break point mode and step through your code line my line.
