Description

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.
