2024-06-04 12:53:46.376 WARN 12 — [io-8080-exec-14] o.a.i.c.m.s.SpecificationLoaderDefault : The metamodel is configured for FULL introspection mode, yet missed org.apache.wicket.markup.html.form.upload.FileUpload of sort UNKNOWN during application start. This happens when type org.apache.wicket.markup.html.form.upload.FileUpload is not eagerly discovered by the metamodel introspection, which (initially) only considers compile-time types via reflection. Run-time types, not explicitly referenced to be included with Spring's class discovery mechanism, might slip this process. Consider importing type org.apache.wicket.markup.html.form.upload.FileUpload with Spring's @Import annotation. Types of sort VALUE should instead register a ValueSemanticsProvider with Spring, to be properly understood by the framework.
