I'll post two Stacktraces of two exceptions into one issue, because they are maybe related.

The code snipped I was messing around:

// assertThat(new PowerClass()).isEqualTo(new PowerClass());
assertThat((Object) new PowerClass()).isEqualTo(new PowerClass());
assertThatObject((Object) new PowerClass()).isEqualTo(new PowerClass());
assertThat((Iterable<PowerClass>) new PowerClass()).contains(new PowerClass());
// assertThat((Comparable<PowerClass>) new PowerClass()).isGreatherThan(new PowerClass());

Context: I was trying to reproduce a case in assertj, which is not possible to solve in an easy way right now.
