Hallo, 

the following test example throws java.lang.reflect.GenericSignatureFormatError

import java.util.*;

public aspect A {

  public interface I {}
  
  public List<?> I.test(Enum<?> ...  values) {
    return null;
  }
  
}

import java.beans.*;

public class T implements A.I {

  public static void main(String[] args) throws IntrospectionException {
    System.out.println(Introspector.getBeanInfo(T.class).getBeanDescriptor());
  }
  
}

This seams only appear in this combination with a generic vararg parameter (not only Enum<?> also List<?> or Map<?,?>) and a complex return type. No problems with 

public String I.test(Enum<?> ...  values) : simple return type
public List<?> I.test(Enum<?> values) : no vararg
public List<?> I.test(Enum ... values) : raw parameter type

Environment:
