Our logs fill up with these Timestamper warnings during a build...

I'm just guessing at what could cause this, but is it might be that Timestamper isn't thread-safe and is having issue with the fact that we are running Maven parallel builds by setting the Maven property -T 1C (one thread per CPU).
