Hi @rafaelweingartner Thanks for the comments.
Just wanted to point out that if the revertSnapshot method is invoked, then
that is actually a failure of the canHandle method to inform the calling code
to not call the revertSnapshot method, so that's why the decision was made to
throw an exception.
I see returning true as your revert was successful and returning false as
it failed (but it was OK for you to ask us to revert because canHandle properly
told you that you could do so).
