-------------------------------------
What about master?
> NullPointerException after reconfiguring via JMX
> ------------------------------------------------
>
> Key: LOG4J2-2770
> URL: https://issues.apache.org/jira/browse/LOG4J2-2770
> Project: Log4j 2
> Issue Type: Bug
> Components: Core, JMX
> Affects Versions: 2.13.0
> Reporter: Bill Kuker
> Priority: Major
>
> Load JMX GUI, go to Log4j Tab, select context, click "Reconfigure with XML
> below".
> the new configuration is accepted and active, but then the subsequent call to
> LogerContextAdmin::getConfigText() throws an NPE.
> Looking deeper, the ConfigurationSource created in
> LogerContextAdmin::setConfigText(...) is created in such a way that
> ConfigurationSource::resetInputStream(), used by getConfigText, is unable to
> create a duplicate of the ConfigurationSource and instead returns null.
> The constructor {{ConfigurationSource(final byte[] data, final URL url, long
> lastModified) }} neglects to set the data member.
