jboss-logging-generator singletons don't play nice with Eclipse APT

While testing m2e-apt on hibernate-search, I got these strange errors :

All the log methods are marked as being duplicate. My gut feeling is this is due to MessageIdValidator being a singleton : all AP work in eclipse reuses the same instance between each incremental builds. So validating the same file more than once lead to these errors.

The generator being a build tool, it doesn't make much sense to use singletons at all, performance-wise.
