Folks,
i am doing this:
logger.debug(line)
where line is null. Please not, if I do sysout(line) before the error
does not happen.
The exception is below. I believe it is because:
toAppendTo.append(config != null && result.contains("${") ?
config.getSubst().replace(event, result) : result);
toAppendTo is null when I put null into .debug thus it crashes.
Shouldn't it be nullsafe? I can imagine people are putting null into
that messages.
Cheers
Christian
