Check the timestamp of the class file as soon as you compile it. If its latest and still your changes are not reflecting, then it simply means that the actual class file that the server is reading and the latest one with the modifications are different.
Why don't you give random SOPs and check if they are printing out to the console? This is the best way to check if your changes are being read by the server.
