AOT causes Logback configuration error when using include #41081
Description
Starting an application with AOT and a custom Logback configuration file (logback-spring.xml) with <include> elements can cause configuration errors (specially with file appenders).
The issue is caused by loading the serialized /META-INF/spring/logback-model and processing the model again.
By processing the model all <include> elements will load the configuration files again and attach the parsed submodules to the existing ones loaded from the serialized file.
This might not cause issues for a ConsoleAppender, but will cause a configuration error for FileAppender (same file name).
Breakpoint in ch.qos.logback.core.model.processor.IncludeModelHandler
Version
Tested with Spring Boot 3.3.1-SNAPSHOT and Java 21
