Description

Methods on the Logger interface that take a Supplier<?> argument currently do not correctly handle the case where the supplied value is of type Message.

Currently, either the Message value will be wrapped in an ObjectMessage, or it will be used as one of the parameter values in a parameterized text message. In both cases, the result of Message.toString() will eventually be logged, rather than Message.getFormattedString().
