Description Archie Cobbs 2012-11-18 10:54:17 EST

Ran AspectJ compiler on this class:

  public class Bug {

    @org.springframework.beans.factory.annotation.Configurable
    public static class ClassA<T extends Interface1 & Interface2> {
    }

    public static class ClassB extends ClassA<ClassB> implements Interface1, Interface2 {
    }

    public interface Interface1 {
    }

    public interface Interface2 {
    }

    public static void main(String[] args) throws Exception {
        System.out.println(ClassB.class.getGenericSuperclass());
    }
  }

Then tried to execute the class' main() method using Java 1.6.0-37 and got OOM:

Using JDK 1.7 we get a java.lang.reflect.GenericSignatureFormatError instead.
