Description

Based on code-with-quarkus project with quarkus-smallrye-openapi (+ RESTEasy Jackson)

The build fails with Quarkus version 2.11.1.Final or higher. With version 2.10.3.Final it works fine.

It has somehow to do with the class DateType and its @Schema annotation, respectively more specific the Date class.

@Schema(implementation = Date.class, name = "DateType")

When using for example String.class as implementation property, the project builds again successfully. This is also the case when using for example String.class as generic parameter.

Example (works fine):

@Schema(implementation = Date.class, name = "DateType")
public class DateType extends Type<String> {

    public String getDefaultValue() {
        return null;
    }

    @Override
    public int compareTo(final Type<String> o) {
        return 0;
    }
}

But when using Date as generic parameter and as implementation property

@Schema(implementation = Date.class, name = "DateType")
public class DateType extends Type<Date> {

    public Date getDefaultValue() {
        return null;
    }

    @Override
    public int compareTo(final Type<Date> o) {
        return 0;
    }
}

the build fails with
