[weld-dev] annotations on Weld proxy classes

[Martin Kouba]

FYI this is not the only problem with Bean Validation and CDI client 
proxies. See also my last comment on CDI-10 [1] and the question posted 
on the HV forum [2].

> org.hibernate.beanvalidation.tck.tests.integration.cdi.executable.CalendarServiceWithCascadingReturnValue$Proxy$_$$_WeldSubclass.createValidEvent()

> org.hibernate.beanvalidation.tck.tests.integration.cdi.executable.CalendarServiceWithCascadingReturnValue.createValidEvent()
> $$$$$$$$$$$$$$$$$DEBUG returnValid = 2 // number of hits having @Valid
