[logback-user] SyslogAppender not logging Throwable message

Hi, We are using the SyslogAppender in logback 0.9.27 and are having an issue with the logging of Throwables. When we are logging an entry like LOG.debug("My message", throwable), "My message" and the throwable's stacktrace is appended to the log, but not the throwable's message. Has anyone else experienced this and know the cause? Regards, Gustav
