[jira] [Created] (LOG4J2-2770) NullPointerException after reconfiguring via JMX

Bill Kuker created LOG4J2-2770:
----------------------------------

             Summary: 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


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.
