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:
{code:java}

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
