[slf4j-user] MessageFormatter: brackets in brackets

[Jean-Luc Geering]

Hi Ceki,

Thanks for the quick reply and for the presentation yesterday (JUGS event)!

I do have a problem with "{{}}" (i.e. no formatting, have "{{}}" in the log),
using slf4j-api-1.5.2 and slf4j-log4j12-1.5.2.

I quickly tested with 1.5.3, and get the same behavior.
Bug? My fault? Do you need more details?

JL

Yes, absolutely. Fixed in revision 1153.

Yes. You can write

log.debug("hello{{}}, "world");

which will produce the message "hello {world}" assumming the logger is enabled 
for the debug level.

Are you observing a different behavior?
