jhl221123 opened a new pull request, #3650: URL: https://github.com/apache/logging-log4j2/pull/3650
This pull request addresses issue #3206, which could lead to a `NullPointerException` when using the shorthand notation for the root logger (e.g., rootLogger = INFO) in `log4j2.properties` without explicitly defining any appender references. To resolve this, the static helper method `LoggerConfig.getLevelAndRefs()` has been updated to ensure that the `LevelAndRefs` container always holds a non-null list of `AppenderRef` objects. When no appenders are specified in the shorthand string, the method has been updated to return an empty list instead of `null`. ## Checklist * Base your changes on `2.x` branch if you are targeting Log4j 2; use `main` otherwise * `./mvnw verify` succeeds (if it fails due to code formatting issues reported by Spotless, simply run `./mvnw spotless:apply` and retry) * Non-trivial changes contain an entry file in the `src/changelog/.2.x.x` directory * Tests for the changes are provided * [Commits are signed](https://docs.github.com/en/authentication/managing-commit-signature-verification/signing-commits) (optional, but highly recommended) -- This is an automated message from the Apache Git Service.
