>             Project: Apache Freemarker
>          Issue Type: Bug
>          Components: engine
>    Affects Versions: 2.3.32
>            Reporter: Christopher Smith
>            Priority: Critical

> 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?
