In my experience, I end up deleting most of my logging statements as I finish pieces of code. They help me a lot when I'm trying to get the basic code going. I might put 5 log statements in a simple method sometimes, if I really can't figure out why it's not working. After I get it fixed I then take those out; whatever software bug I had in there won't be coming back. So I never use the if(logLevel == DEBUG) idiom. And I always use the java.util.logging classes, because I know they will be there, no matter what is or is not on the classpath, or no matter what kind of classloader problems might be happening.
