    Annotation with priority >= 0 are guaranteed to be run after Jenkins is up. Negative priorities are run before startup on best effort basis. (It might not happen before for ExistingJenkinsController, PooledJenkinsController and possibly others).
    Annotations that skips execution are encouraged to run before Jenkins is booted up to save time. Note, that these implementations can not inject Jenkins for obvious reasons.
