    Description

      EqualsBuilder.reflectionEquals() does not hold transitivity when comparing two subclasses extending a common superclass. For example:

      Given that both class D and E are subclasses of class C, C == D and C == E should imply D == E. However EqualsBuilder.reflectionEquals(D, E) returns false when both EqualsBuilder.reflectionEquals(C, D) and EqualsBuilder.reflectionEquals(C, E) return true.

      A junit test is provided as attachment.
