As reported indirectly in PR-43 and PR-43 something has changed in Spring's SortedResourcesFactoryBean between Spring Boot 3.5.7 to and 3.5.8 which now makes PreLiquibase throw exception.

Previously it was possible to instantiate that factory with non-existing resources, but now an exception will be thrown during initialization of the factory if non-existing resources are in its list.

I believe the Spring team needs to be made aware that they made an regression. But we can definitely work around it in Pre-Liquibase.
