Trejkaz reopened MANT-74:
-------------------------
While a configuration issue is *not* a bug, I am not convinced that this is a
configuration issue in the first place. Who says that you can't have zero
excludes? I couldn't find anything on the page for the plugin to indicate that
it's prohibited and had to search forums to find hints that it might work as a
workaround.
But in any case, thinking about it *rationally*, there are two possible
outcomes, depending on whether you think it's legal or not. Either:
(a) It is legal to specify the excludes element without any children. In this
case, it should proceed as if the element was absent. Or:
(b) It is illegal to specify the excludes element without any children. In this
situation, the error should say something like: "It is illegal to specify the
excludes element without any children. You should remove the element."
Irrespective of whether it is legal or not, throwing a ClassCastException (or
any non-descriptive exception) back to the user is never acceptable.
