I am trying to upgrade from Logback 1.5.12 to 1.5.13 and be0b5e0 is affecting us.

We do have a number of additional classnames that we set in the PATTERN_RULE_REGISTRY for our own support. It looks like we should be providing a supplier now. If I understood this correctly, this is surprising in a patch release.

If this is indeed what we should be doing now, how do we maintain compatibility with Logback < 1.5.13 whist providing support for the latest patch release?
