>                 URL: https://issues.apache.org/jira/browse/LOG4J2-1084
>             Project: Log4j 2
>          Issue Type: Bug
>          Components: API
>    Affects Versions: 2.3
>            Reporter: Philipp Schneider
>            Priority: Minor
>              Labels: easyfix
>   Original Estimate: 1h
>  Remaining Estimate: 1h

> In the class org.apache.logging.log4j.LogManager in the API package there is a logical
problem with finding the factory.
> In the static initialization block starting at line 70 you try to create a factory instance
from the factory class specified in the property "log4j2.loggerContextFactory". If that fails
you try to find the class in all the supplied providers.
> The problem comes in line 104. You check whether the list of factories is empty and if
it is not you automatically assume that there is more than 1 provider which has that class.
> Because of this I get the following logging entries on each startup:
> WARN StatusLogger Multiple logging implementations found: 
> Factory: org.apache.logging.log4j.core.impl.Log4jContextFactory, Weighting: 10
> Using factory: org.apache.logging.log4j.core.impl.Log4jContextFactory
> As you can see, it clearly outputs only a single possible factory and also uses that
one.
> Hope to see this fixed in 2.4 since it is really a minor issue.
