Per Matt Benson on the list:

I would challenge
BootstrapConfigurationWithValidatedExecutableTypesContainingNONETest
as defying the specification. The current version says at
http://beanvalidation.org/2.0/spec/#integration-general-executable and
in the code for ExecutableType that NONE is essentially ignored in the
presence of other types (and effectively, always). I see nothing to
dictate that NONE should be treated differently in the XML descriptor
than elsewhere.
