PF4J-Spring is not compatible with Spring Boot 3

[charbelsdk]

The issue is with the init method in the SpringPluginManager class.
The method is annotated by javax.annotation.PostConstruct which is deprecated and replaced by jakarta.annotation.PostConstruct.
The SpringPluginManager class is initiated without loading the plugins, thus failing to inject and load the extensions

I think that you talk about Spring 6 not Spring 3.
According #80 it seems to work as as expected with Spring 6.

sorry, I meant spring boot 3.x.x

[charbelsdk]

You can see the javax.annotation.PostConstruct in the note https://docs.spring.io/spring-framework/reference/core/beans/annotation-config/postconstruct-and-predestroy-annotations.html is deprecated.
The init method annotated PostConstruct is used to load and start the plugins.
However, since the annotation has been replaced in the new spring boot version, the method init() has not been launched.

Two possible solutions:

• create a new Spring6PluginManager that extends SpringPluginManager, override init method and add jakarta.annotation.PostConstruct annotation on it
• add jakarta.annotation.PostConstruct annotation on SpringPluginManager (in this case both PostConstruct are added)

But, according Spring Upgrading to Version 6.0:

The JSR-330 based @Inject annotation is to be found in jakarta.inject now. The corresponding JSR-250 based annotations @PostConstruct and @PreDestroy are to be found in jakarta.annotation. For the time being, Spring keeps detecting their javax equivalents as well, covering common use in pre-compiled binaries.

I understood your point of view, but why #80 confirmed that current version works with Spring 6 out of the box?
