REST Data Panache with ResteasyReactive: field 'id' was not found error

Describe the bug

When using REST Data Panache with ResteasyReactive for entity that has an id field not named “id” application crashes on start with exception:

Caused by: io.quarkus.builder.BuildException: Build failure: Build failed due to errors
	[error]: Build step io.quarkus.resteasy.reactive.links.deployment.LinksProcessor#initializeLinksProvider threw an exception: java.lang.RuntimeException: Class 'java.lang.Object' field 'id' was not found
	at io.quarkus.resteasy.reactive.links.deployment.LinksProcessor.getFieldInfo(LinksProcessor.java:146)
	at io.quarkus.resteasy.reactive.links.deployment.LinksProcessor.getFieldInfo(LinksProcessor.java:144)

example entity:

public class ExampleEntity extends PanacheEntityBase {
    @Id
    long companyId;
}

example resource:

@ResourceProperties(path =  "/example")
public interface ExampleResource extends PanacheEntityResource<ExampleEntity, Long> {
}

Data Panache generate resource with path “/example/{id}” so io.quarkus.resteasy.reactive.links.deployment.LinksProcessor#getFieldInfo scans for field “id”, ignoring the fact that entity can have id field with whatever name but with annotation @Id

Expected behavior

REST Data Panache with ResteasyReactive should work with an entity with id field not named “id” but annotated with @Id

Actual behavior

Can you change the type of your id to Long instead of the primitive type long ?

By the way, this is the default ID field provided by PanacheEntity so you better use PanacheEntity instead of PanacheEntityBase.
