Hello Ralph, The LoggingEvent class changed to a large extent in SVN trunk. Replacing CallerData with StackTraceElement is yet another incompatible change. Worrying about backward compatibility for CallerData and not for the rest would be pretty pointless. Ralph Goers wrote:
The only concern I would have is that it would break an existing user's code to remove it. I realize the version is still 0.9.something, but at this point Logback is being used in production, probably in lots of places.
What I would suggest is to change all the Logback code to use StackTraceElement but deprecate CallerData and the getCallerData method and then have CallerData extend StackTraceElement as a wrapper. Make sure you add getStackTrace to the LoggingEvent. getCallerData could then create the CallerData array from the StackTrace array.
