Hi all, I have a use case where I need to log some byte[] and the current default behavior of slf4j seems to be to print decimal values for each item in the array. I would prefer hex notation instead and can't seem to find any way to configure that behavior. It seems to me it's hard coded using LoggingEvent.getFormattedMessage and MessageFormatte.byteArrayAppend. Is there any way to change this behavior? The only thing coming into my mind is overriding LoggingEvent with a custom getFormattedMessage method, but I don't know how to get Logback using that internally. And I wouldn't want to re-implement MessageFormatter because it's most interesting methods are private. Any other options like parsing the formatted message afterwards and convert it to contain hex bytes instead? Though it sounds a lot more difficult than converting into the format I want in the first place. Thanks for your help!
