[logback-dev] logback-decoder

Thu Jun 13 17:36:30 CEST 2013

Thanks for the test case. That's helpful.

While similar, this problem is actually different from the first.
Originally, the layout pattern couldn't be parsed. With that problem fixed,
the parser now trips up on the input line. It sounds like the logger-name
parser is using a greedy regex matcher (similar to the problem with the
layout pattern). I'll look into this tonight.
