[weld-dev] TCK Interceptors Classes

[Marius Bogoevici]

Gavin,

This is very ambiguous, as the 1.1 version of the Interceptors 
specification states very clearly the signature rules for defining 
lifecycle interceptor methods on interceptor classes and target classes.

Also, this could mean that an interceptor class can specify two 
different @PostConstruct or @PreDestroy methods, which would refer to 
different targets (the intercepted instance/the interceptor itself), but 
the specification says very clearly:
"At most one method of a given interceptor class can be designated as an 
around-invoke method, an around-timeout method, a post-construct method, 
or pre-destroy method."

Also, it is not very clear to me what would be the benefit of a separate 
@PostConstruct/@PreDestroy method for the interceptor itself, as 
interceptor lifecycles are virtually the same as for the target objects.
