> Key: LOG4J2-1658
> URL: https://issues.apache.org/jira/browse/LOG4J2-1658
> Project: Log4j 2
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.7
> Environment: Windows, JVM 1.8.0_66
> Reporter: Leon Finker
> Assignee: Remko Popma
> Fix For: 2.8
>
>
> We have a custom OSGi based application. We specify
> Log4jContextSelector=org.apache.logging.log4j.core.selector.BasicContextSelector.
> We initialize log4j through
> Configurator.initialize("main", logConfigPath);
> Starting from log4j2 2.7 above line fails due to
> NPE/ExceptionInInitializerError in LogManager static init block. I found a
> work around by specifying disableThreadContextMap=true. This is 2.7 specific
> change.
> {noformat}
