I get the same result from your code. Only thread-2 outputs something,
thread-1 comes before but the call comes up empty.:
write thread-1
done thread-1
write thread-2
[TEST] [INFO ] thread-2 - message
done thread-2
Any call to LogManager makes it succeed:
LogManager.getContext(false);
th1.start();
th2.start();
th1.join();
th2.join();
New output:
write thread-2
write thread-1
[TEST] [INFO ] thread-2 - message
done thread-2
[TEST] [INFO ] thread-1 - message
done thread-1
The funny thing is that the first thread to arrive is initialized with
ERROR level instead of the ALL that is given to root. In other words it
seems that the config hasn't affectuated the root logger yet:
write thread-1 to thread-1:ERROR in 1829164700
done thread-1
write thread-2 to thread-2:ALL in 1829164700
[TEST] [INFO ] thread-2 - message
done thread-2
So when you increase our logging level in the calls:....
write thread-1 to thread-1:ERROR in 1829164700
09:05:46.200 [Thread-0] ERROR thread-1 - message
done thread-1
write thread-2 to thread-2:ALL in 1829164700
[TEST] [ERROR] thread-2 - message
done thread-2
You also see that it still uses the old pattern, in other words the XML
hasn't been processed yet or taken affect.
So the call proceeds but just acts on an uninitialized logger system.
That's all I can do from here for now. Maybe better make Jira?.
----------------------
by the way is the list so defunct or have I been put on moderation? :P
:( :?.

Hi,
I have wrote a very simple example which has a behaviour I do not expect:
If I call LogManager.getLogger(..) from two threads, only one of the
loggers logs what I'd expect but if I add an additional call to
LogManager.getLogger(..) before the threads are started, I see what I'd
expect so it looks like there is a problem in multi threaded initialization.
You can fine the code and the configuration here:

Am I doing something wrong ?
