Panache when used with method reference

Describe the bug Quarkus fails to augment a Panache operation when using method reference rather than a the corresponding method invocation in a lambda expression (like in a map).

Expected behavior Method reference should works just as standard method invocation

Actual behavior Whenver a method reference to a Panache Operation is used the operation fails with a stack trace indicating the Panache method has not been augmented

Caused by: java.lang.IllegalStateException: This method is normally automatically overridden in subclasses: did you forget to annotate your entity with @Entity?

To Reproduce Steps to reproduce the behavior: Here you have a reproducer: https://github.com/danielpetisme/panache-method-reference-issue Simply clone and go with ./mvnw compile test In a nutshell

    @GET
    @Path("/with-method-invocation/{id}")
    @Produces(MediaType.TEXT_PLAIN)
    public String getFruitNameWithMethodInvocation(@PathParam("id") Long id) {
        return Optional.of(id).map(it -> Fruit.<Fruit>findById(it)).map(it -> it.name.toUpperCase()).orElse("Error");
    }

    @GET
    @Path("/with-method-reference/{id}")
    @Produces(MediaType.TEXT_PLAIN)
    public String getFruitNameWithMethodReference(@PathParam("id") Long id) {
        return Optional.of(id).map(Fruit::<Fruit>findById).map(it -> it.name.toUpperCase()).orElse("Error");
    }

 @Test
    public void testWithMethodReference() {
        given()
                .when().get("/fruits/with-method-reference/1")
                .then()
                .statusCode(200)
                .body(is("APPLE"));
    }

    @Test
    public void testWithMethodInvocation() {
        given()
                .when().get("/fruits/with-method-invocation/1")
                .then()
                .statusCode(200)
                .body(is("APPLE"));
    }

The second test will fail
