The wording and spirit of Throwable.addSuppressed API argues it should
be used when you have *another* exception and only one needs to be
propagated. In the test case like mine you can *single* exception that
needs to be propagated, so there is no reason to suppress any other

That said, imposing that additional requirement without even
mentioning this in spec violates the "principle of least
