Hello
Could somebody please explain if it's ok when statusListener.start method
is invoked twice? I.e. can it be bug rather than feature?
As far as I understand it's getting invoked from LogerFactory.bind method:
private final static void bind() {
...
Set<URL> staticLoggerBinderPathSet = null;
// skip check under android, see also
http://jira.qos.ch/browse/SLF4J-328
if (!isAndroid()) {
staticLoggerBinderPathSet = findPossibleStaticLoggerBinderPathSet();
reportMultipleBindingAmbiguity(staticLoggerBinderPathSet);
}
// the next line does the binding
StaticLoggerBinder.getSingleton();
<---fist from here
INITIALIZATION_STATE = SUCCESSFUL_INITIALIZATION;
reportActualBinding(staticLoggerBinderPathSet);
replayEvents();
<---then from here
...
}
The stacktraces:

I'm trying to setup logging in an entangled ear app consisting of a bunch
of separate war modules using SiftingAppender
and JNDIBasedContextDiscriminator deployed to IBM Liberty. Can't reproduce
it in simpler configuration. So far I've just removed all modules but one
and start still invoked twice (the bp in AuthorisationListener.java:34 is
triggered only once).
Any help is highly appreciated.
logback version is 1.1.7.
Best regards, Eugene.
