New Baseline: Spring Boot 3 and Java 17

[ThomasVitale]

• Minimum supported version of Java is now 17
• Minimum supported version of Spring Boot is now 3.2

Spring Boot versions older than 3.2 reached EOL and will not receive any further support nor security patches. It would be a security risk to continue using EOL-ed versions in this LangChain4j project.

More information: https://spring.io/projects/spring-boot#support

@langchain4j what do you think? The tests are failing because the values from the environment variables are empty (e.g. the OpenAI API Key). I'm not sure why.

[langchain4j]

@ThomasVitale thank you, looks good!
Secrets (env vars) are not propagated probably because you are running it from your fork, let me try to rerun it

[ThomasVitale]

Right, that makes sense. Next time, I'll create a branch directly from here instead of a fork.
Thanks for the review!

@ThomasVitale can't make it inject secrets from the fork :( I have run it locally, tests in anthropic are failing with

This is probably due to @RetryingTest?

[ThomasVitale]

@langchain4j I'll have a look, thanks

[ThomasVitale]

It looks like the JUnit Pioneer dependency doesn't support running with Spring Boot 3 (junit-pioneer/junit-pioneer#810). I'll see if I can find some workaround.

[ThomasVitale]

@langchain4j as agreed, I updated the PR removing the JUnit Pioneer extension. I couldn't reproduce the error on a Spring Boot app created from start.spring.io, so it's probably something specific to the project setup involving Maven SureFire, Java 17 and Spring Boot 3.

@ThomasVitale thank you!
