> While testing [m2e-apt|https://github.com/jbosstools/m2e-apt] on [hibernate-search|https://github.com/hibernate/hibernate-search], I got these strange errors :
> !jbosslogging-ap-errors.png!
> All the log methods are marked as being duplicate. My gut feeling is this is due to [MessageIdValidator being a singleton|https://github.com/jboss-logging/jboss-logging-tools/blob/4b437dd4c7626f4c5da9fb99923fd2cac4e87a78/src/main/java/org/jboss/logging/processor/validation/MessageIdValidator.java#L44] : 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.
