Description

There are perfectly valid cases where you may want to output a log message with no elements displayed, i.e. with showExchangeId=false, showBody=false, etc.

For example, when you want to print a "signal" log line for a particular transaction and you're already using MDC logging with breadcrumbs enabled. You may already have all the info you need: logging category, severity, breadcrumbId. You are not interested in anything else.

Currently, disabling all elements leads to a NPE.
