The following assumes you're using ant to control compiles, etc. 

I've seen that problem in the past, but not recently. However, it never 
hurts to add a 'clean' <target>, that removes all *.class and *.jar files 
that a build generates, to your build.xml and running "ant clean; ant" 
periodically.

If you follow the 'large project' advice and separate *.class files from 
the source files, then using 'ant' or an equivalent program to manage 
compilation will make using the separation rather easier.
