> 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.
