ClasspathResourceResolver unable to resolve from nested jar

[tschlat]

Citrus Version 4.x-SNAPSHOT with Spring-Boot 3.2

Expected behavior The ClasspathResourceResolver should be able to resolve resources from nested jars. Specifically, the org.citrusframework.spi.TypeResolver, which is responsible for resolving classpath resource mappings, is failing to resolve these mappings. For example, it should be able to resolve resources located in citrus-validation-json-4.x/META-INF/citrus/variable/extractor/segment/.

Actual behavior The ClasspathResourceResolver is unable to resolve these resource mappings when packed into a Spring Boot jar archive. In this case, the containing jar is nested within the Spring Boot executable jar. It appears that there has been a change in the representation of nested jar URLs from:

jar:file:/C:/work/IdeaProjects/myProject/target/myproject-1.0.0-SNAPSHOT-executable.jar!/BOOT-INF/lib/citrus-validation-json-4.0.2.jar!/META-INF/citrus/variable/extractor/segment/ to jar:nested:/C:/work/IdeaProjects/myProject/target/myproject-1.0.0-SNAPSHOT-executable.jar!/BOOT-INF/lib/citrus-validation-json-4.0.2.jar!/META-INF/citrus/variable/extractor/segment/

And jar:nested is not properly handled by the Citrus ClasspathResourceResolver.

This change in Spring Boot from 3.1.x to 3.2.x aligns with the documentation:

@christophd detected by @postfinance in (company-internal) release candidate for 4.1.0. should be fixed before the release, I think.
