> h3. Given:
> * A functional interface `IStillFunctional` with a method `foo` and a
> default-method `bar`.
> * A java method `doConsume(IStillFunctional)` (defined in a Java-Class)
> I get an `IllegalAccessException` when I pass a Closure to the `doConsume`
> method and then call the default-method `bar`.
> h3. Stacktrace:
>

> I attached a minimal project with this issue to the ticket.
>
> h3. Observations:
> * The issue seems to happen in
> org.codehaus.groovy.runtime.ConversionHandler#invoke.
> * The issue does not happen when the Consumer-Class is defined in a Groovy
> file.
> * The issue did not occur under JDK 11
