And now allows the Map to be modified? If so, please revert.
The contents of LogEvents are not supposed to be allowed to be modified by
components once they are passed to the Logger to be logged. Allowing a Filter
or an Appender to modify the contents means that other Appenders will see the
modification if they get LogEvent later in the processing. We don't allow that.
Instead, a copy of the LogEvent must be made for use by that Appender or
components derived from it.
