> See file attached to reproduce the problem: E1 is an exception class, E2 extends from E1 but define only the constructor with {{String}}.
> using new E2(null) end up calling {{E1(Throwable)}} => calling {{initCause}} then fails because the cause has been already been set.
> I am expecting {{E1(String)}} to be called...
> {code}
