[jira] [Created] (LOG4J2-1658) 2.7 -
ThreadContextAccess.getThreadContextMap NPE when specifying
BasicContextSelector
Leon Finker created LOG4J2-1658:
-----------------------------------
Summary: 2.7 - ThreadContextAccess.getThreadContextMap NPE when specifying BasicContextSelector
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
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.
