    getDeclaringClass throws error

    Ragnar Rova Newbie

      Hi

       

      Why does the following testcase fail with IncompatibleClassChangeError ?

       

      package foo;
      
      import javassist.*;
      
      import org.junit.*;
      
      public class GetDeclaringClassTest {
      
          static class Foo {
              String bar;
          }
      
          @Test
          public void get_declaring_class_should_not_throw_error()
                  throws NotFoundException, CannotCompileException {
              ClassPool pool = ClassPool.getDefault();
              CtClass cc = pool.get(Foo.class.getName());
              cc.setName(Foo.class.getName() + "$BackRef");
              Class<?> klass = cc.toClass();
              klass.getDeclaringClass();
      
          }
      }

          Error was

           

          java.lang.IncompatibleClassChangeError: foo.GetDeclaringClassTest and foo.GetDeclaringClassTest$Foo$BackRef disagree on InnerClasses attribute

           

           

          Is it because I have not modified the outer class? How can I create a copy of a inner class (and add one field) without getting this error?
