----------------------------------------------------------------------

The project is available on Github at https://github.com/vendorflow/vendorflow-jsonapi. Running {{./mvnw test}} with a Java 17 SDK (I am using {{OpenJDK 64-Bit Server VM Temurin-17.0.9+9 (build 17.0.9+9, mixed mode, sharing)}}) will demonstrate the failure. (The {{release}} is set to 11, but that makes no difference.) The current master HEAD revision is c924c397b10746bef890346dc27df084c5a2de72.

> I am using Freemarker in an annotation processor to generate code. I supply an instance of {{javax.lang.model.element.TypeElement}}, which implements {{QualifiedNameable}}, to the template model and use {{element.qualifiedName}} as a template variable.
> My code works fine under Java 11, but after updating the compiler to Java 17 (even with Java 11 compliance settings), I am receiving an {{IllegalAccessException}}.
> There seems to be a severely deficient implementation in the encapsulation of Java internals that does not make methods that implement an interface accessible, but perhaps it's possible to get the {{Method}} handles for the property accessors on interfaces? I see that {{ClassIntrospector#discoverAccessibleMethods}} tries to do this, but perhaps it's not taking into account JPMS?
