    Infinite loop at bootstrap with self-referencing parameterized interfaces

    Francois Swiegers Newbie

      Good day,


      I have the following interfaces in my workspace:


      public interface SomeInterface<T> {
      
           AnotherInterface<T> doSomething();
      
           public interface AnotherInterface<T> extends SomeInterface<T> {
           }
      
      }
      



      When I try to bootstrap Weld, I get the following StackOverflowError

      This happens only when



      1. the interfaces are parameterized

      2. the second interface extends the first and

      3. the first interface has a method with the second interface as a return type



      Also note that these are not interfaces to CDI managed beans at all - I'm not sure why Weld is even attempting to read them.
