I've to work on different projects and one of them is using Java 8 and another Java 17. I was working with Java 17 last week and now I'm trying to revert my configurations to work with Java 8.
These are my configurations
$ mvn --version
Apache Maven 3.8.4 (9b656c72d54e5bacbed989b64718c159fe39b537)
Maven home: /usr/local/Cellar/maven/3.8.4/libexec
Java version: 1.8.0_251, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk1.8.0_251.jdk/Contents/Home/jre
Default locale: en_BR, platform encoding: UTF-8
OS name: "mac os x", version: "10.16", arch: "x86_64", family: "mac"
$ java -version
java version "1.8.0_251"
Java(TM) SE Runtime Environment (build 1.8.0_251-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.251-b08, mixed mode)
I removed all the folders inside ~/.m2 also.
My configs in IntelliJ are:
Project Structure > Project > Project Settings > Project
SDK: OpenJDK 1.8
Language Level: SDK Default
Project Structure > Project > Project Settings > Modules
Module SDK: Project SDK (OpenJDK 1.8)
Preferences | Build, Execution, Deployment | Compiler | Java Compiler
Project Bytecode: 8
Preferences | Build, Execution, Deployment | Build Tools | Maven | Importing
JDK for importer: Use Project SDK
Run/Debug Configurations > Tomcat 9.0.53
JRE: OpenJDK 1.8
Am I missing something? Why this error is thrown?

CodePudding user response：
The issue appears to be with Tomcat being incompatible with log4j 2.15 when running on Java 8.
See the related issues for other app servers:
Normally such issues are fixed by the app server update. If it's not possible, use log4j library without JEP-238.
