Review comment:
Wrapping every `LOG.debug` in an `if` increases method complexity and may
trigger a new Sonar warning above a threshold (it does here). I think log
statements are safe to call unconditionally (both for performance and for
Sonar) as long as their arguments are not eagerly evaluated. Using
placeholders and passing existing objects as arguments should be OK.
