I don't know why it is a race condition. The error just happened once and I could not reproduce it.
But I don't know enough about the internals of Tomcat to what really happens there. Just mailed it, so somebody who knows can do something with (or not).

Hi, I don't think that's a race condition (it's race, not racing, by the way ;)). But I'm curious to hear your reasoning as to why you suspect that?

Today I got this when doing a request during Tomcat startup. Can it be a racing condition?
Greetings,
