Several places in the Skara code uses log.throwing for logging exceptions, for example https://github.com/openjdk/skara/blob/53bfe81aac9524da410607ef9e148fef7bda7e74/bots/notify/src/main/java/org/openjdk/skara/bots/notify/RepositoryWorkItem.java#L292 . This unfortunately logs them at the "finest" level, which may end up being filtered when the logs are stored.

More recent code has switched to using log.log(level, msg, exception) instead to allow setting a reasonable level, like https://github.com/openjdk/skara/blob/53bfe81aac9524da410607ef9e148fef7bda7e74/bots/notify/src/main/java/org/openjdk/skara/bots/notify/RepositoryWorkItem.java#L129 . It would be nice to update all the log.throwing calls to use log.log instead.
