Can't initialize classes annotated with @Repository after upgrade to Spring Boot 3.10

Question

We decided to start upgrading from Spring 2.7.0 to Spring 3.x. First I upgraded to Spring 3.0.x but, due to a spring bug, the beans were not initialized so I switched to 3.1.0. I fixed all the compilation errors, changed javax to jakarta, upgraded the spring-security configuration and so forth. Now, the application starts but crashes at initialization. Here's a log snippet.

The error is the following

Answer 1

Always looks the Caused by: in the error logs, looks like need to upgrade the antlr4-runtime jar to latest. Check using the mvn dependency:tree about the version, if not update to the latest

<dependency>
   <groupId>org.antlr</groupId>
   <artifactId>antlr4-runtime</artifactId>
   <version>4.13.0</version>
</dependency>
