> In log4j 2, I would like to trim the end of messages written to the console
> appender when size is above a specified threshold.
> I looked at the
> http://logging.apache.org/log4j/2.0/manual/layouts.html#PatternLayout docs
> but can see no option to truncate the end of the "msg" field.
> "%.1000msg" will leave only the last 1000 chars of the message.
> This is not good for me because in Java the most inner frames in stack trace
> are printed at the beginning of the message.
