[hibernate-dev] on broken usage of logger

Hi all, I'm having a chat with Hardy about how we used the Logger in some cases, and it turns out there's some confusion about log.debugf vs log.debug log.tracef vs log.trace So the "F" variant is needed when we want to format a message, in this case we should make sure the number of parameters matches exactly. Also when the string is generated, like in the case of: https://github.com/Sanne/hibernate-core/commit/3c5f8a568de99c7a6532647ab7... it's very important that we do NOT use the formatting method, but just a plain "log.debug( string )", otherwise it might happen at runtime that the dynamically generated string contains some characters which the String formatter might want interpret as placeholders, which are missing. (HHH-6817) In practice, it seems like a bad idea to allow a dynamically generated formatting string at all; formatting strings as defined on the Logger interface are safer; In case a dynamically generated message is to be generated, we should all make sure to pick the correct method signature; we're wondering if there could be a reasonable proposal to make the checks of the annotation processor stricter and validate for this, but there are some (rare) valid use cases so just throwing compilation errors would be nasty.
