# Summary [NIFI-10580](https://issues.apache.org/jira/browse/NIFI-10580) Upgrades SLF4J from 1.7.36 to 2.0.6 and upgrades Logback from 1.2.11 to 1.3.5. SLF4J 2.0 does not introduce any breaking API changes to standard interfaces, but changes the initialization process, which requires a minimum Logback version of 1.3.0. Logback 1.4.0 requires Java 11, so Logback 1.3.5 is the current compatible version. Spring Boot 2.7 provides a logging system implementation based on Logback 1.2, but the initialization process is not compatible with Logback 1.3. NiFi Registry does not depend on the Spring Boot logging initialization, so disabling the initialization using a System property resolves startup issues. ZooKeeper has a dependency on Logback, which creates issues when running some tests, but excluding Logback resolves those issues. The ZooKeeperMigratorTest.groovy creates a test ZooKeeper server using an Apache Curator class that relies on Logback 1.2. This test is written in Groovy and uses Spock, so this pull request removes the test class. # Tracking Please complete the following tracking steps prior to pull request creation. ### Issue Tracking - [X] [Apache NiFi Jira](https://issues.apache.org/jira/browse/NIFI) issue created ### Pull Request Tracking - [X] Pull Request title starts with Apache NiFi Jira issue number, such as `NIFI-00000` - [X] Pull Request commit message starts with Apache NiFi Jira issue number, as such `NIFI-00000` ### Pull Request Formatting - [X] Pull Request based on current revision of the `main` branch - [X] Pull Request refers to a feature branch with one commit containing changes # Verification Please indicate the verification steps performed prior to pull request creation. ### Build - [X] Build completed using `mvn clean install -P contrib-check` - [X] JDK 8 - [ ] JDK 11 - [ ] JDK 17 ### Licensing - [ ] New dependencies are compatible with the [Apache License 2.0](https://apache.org/licenses/LICENSE-2.0) according to the [License Policy](https://www.apache.org/legal/resolved.html) - [ ] New dependencies are documented in applicable `LICENSE` and `NOTICE` files ### Documentation - [ ] Documentation formatting appears as expected in rendered files -- This is an automated message from the Apache Git Service.
