It would be helpful to see the whole class, so that I can fully
understand the problem. Is it that the equals() comparison is in some
way not symmetrical? Does this only affect the KerberosPrincipal class
or also when comparing this class with other classes?

Generally, implementing equals() is the same like overloading == in C++.
But you're right, you should get the hashCode() thing right.
