If the file hasn't changed then it must be that the javac used is a 
newer one that produces this warning; or a warning flag has been enabled 
that isn't normally.

Your build log is full of clock skew warnings so things may be getting 
compiled out of order and with the wrong javac options being applied. 
You need to fix that first and see what happens with a regular build.
