---------------------------------------
Hi [~jayeshnetravali],
Thanks for reporting the issue. This seems like a typo in the code and will be
shortly fixed.
> log4j2 Spring Cloud config integration with MTLS gives NullPointerException

> Hello
>
> I am trying to use the log4j2 Spring cloud config integration capabilities
> and have been referring to the sample application on the github project
> [https://github.com/apache/logging-log4j2/tree/release-2.x/log4j-spring-cloud-config/log4j-spring-cloud-config-samples]
> When I try to configure a MTLS HTTPs URL of my cloud config server in the
> bootstrap.yaml of my client application which needs to fetch the log4j2.xml,
> I get a NPE in the
> org.apache.logging.log4j.core.net.ssl.SslConfiguration.createSslContext(
> final boolean loadDefaultKeyManagerFactory, final boolean
> loadDefaultTrustManagerFactory) method when the
> SSLContext.getInstance(this.protocol); is invoked. On debugging I see that
> the protocol being passed from the SslConfigurationFactory to the
> SslConfiguration is "https" which causes SSLContext.getInstance() to throw an
> exception and thus no sslContext is created. I have attached the stacktrace
> for your reference.
> Below is my configuration. Please let me know if I am missing something.
> logging:
