[logback-user] Logging from different threads

[Lukas Zapletal]

Hi

I HAVE FOUND THE SOLUTION!

The class not being logged is in very very long package. Its a :

com.pike.puma.wm.isd2dita.core.g.project.server.pkg.isobjecttype.isobject

I am using %logger{20} pattern and it seems this very long package cannot
even fit in this pattern (with only 20 characters permitted). I have raised
this value to 200 and now it works - the package and the log record appears:

com.pike.puma.wm.isd2dita.core.g.project.server.pkg.isobjecttype.isobject.ISObjectContentGenerator

I would suppose that if the name of the logger is longer and cannot be
shortened to the limit something like 

i.i.ISObjectContentGenerator 

will appear throwing away beginning of the name. Not at all. I have also
tried %logger{0} to see only "ISObjectContentGenerator" but this did not
work too.

Is this a bug? I am using version 0.9.9.
