Could you add testcases for corner cases:
no fields:
  interface I1 {
  }
  class NoFields1 {
  }
  class NoFields2 extends NoFields1 implements I1 {
  }

no parent fields:
  class NoParentFields extends NoFields1 implements I1 {
    int i1 = 1;
    int i2 = 2;
  }

only parent fields:
  class Parent1 {
    int i3 = 3;
  }
  class OnlyParentFields extends Parent1 {
  }
