Hello,

I'm running into this problem. It already existed in hawtio as well https://github.com/hawtio/hawtio/issues/2755

SLF4J: Actual binding is of type [org.apache.logging.slf4j.Log4jLoggerFactory]
Exception in thread "main" java.lang.ExceptionInInitializerError

FAILURE: Build failed with an exception.

Would it be possible to make it working with logback?

Hello,

What would be the steps to reproduce this ?

Hello,

I'm using Spring Boot without further logging libraries. It uses logback by default.

My guess is there is no transitive dependency involved that is responsible for this problem.

I just tried with a Spring Boot app which embeds camel-plantuml 1.4.0, and it works as expected. I don't have those error. I tried with latest Spring Boot version (2.7.3). Which version do you use ?
