Classname info in logfile is difficult to read

This is a constraint due to using log4j - afaik, you cannot change it in log4j.
See also openhab/openhab-addons#384

So that leaves three options:

• change pax-logging to use logback rather than log4j. Pax logging supports all loggers.
• add a custom layout formatter to use with Log4J
• change the format to print the fully qualified name without trimming

Leaving it as is, will cause much frustrations (at least for me...)

I would still tend to go with logback again.
I only wonder if @maggu2810's fear (openhab/openhab-addons#384 (comment)) is right and that this would mean that we cannot use log:set? This is currently the only way to enable debug logging, so this is something we should not lose.

The pax-logging-service log4j backend is the only one that implements all the log commands correctly.
I had a look at the other implementations (log4j2 and logback) and there is still a bit of work to be done before those support all the commands.
I had a first attempt at using a custom formatter, but it turns out that all the log4j classes have been repackaged inside the pax-logging-service jar and none of them have been exported, so these aren't accessible causing this approach to fail.
I'll investigate further to see how we can get this to work decently.

[dvanherbergen]

The logging service will change to log4j2 in karaf 4.1.0. This will allow the use of new layouts, so it doesn't make any sense to make changes to the logging approach now.

Sounds good!
