             Summary: Add nullability-related annotations for better documentation and static analysis
                 Key: LOG4J2-3448
                 URL: https://issues.apache.org/jira/browse/LOG4J2-3448
             Project: Log4j 2
          Issue Type: Improvement
          Components: API
            Reporter: Matt Sicker


Nullability annotations can be used by static analysis tools, IDEs, and even Kotlin, to better check for potential NullPointerException errors or redundant null checks. To avoid introducing an additional dependency here, these annotations can be defined in the API. At minimum, some form of {{@Nonnull}} and {{@Nullable}} should be added.

Alternatively, as these are compile-time annotations anyways, it may be possible to use a third-party annotation library here as long as it's also compile-time only.
