Re: [weld-dev] AnnotatedType and the SPI

Yeah, I misread your email. We always merge annotations (I just checked the code for any annotated thing), which IMO is wrong. We should always take the annotations from the Annotated* if it exists. What we do also do, is take the info from reflection if someone misses out the Annotated{Method,Field,Parameter, Constructor} object from the AnnotatedClass definition. Whilst this does make sense for Methods, Fields and Constructors (omitting them is ok), it doesn't work for parameters (Java requires you to provide all parameters). So IMO it should be an exception to not mirror accurately the class definition in the AnnotatedClass. https://jira.jboss.org/jira/browse/WELD-371 https://jira.jboss.org/jira/browse/WELD-372 On 12 Jan 2010, at 11:52, Stuart Douglas wrote: > I will double check then, I just had a quick look so there is a good chance I may have been wrong about the behaviour.

If an AnnotatedParameter is missing it uses the Annotations on the underlying class, however if a field definition is missing it treats it as having no annotations (I have not actually tested this, just has a quick look at the code, so I could be wrong). > > We should *always* merge the annotations from the underlying class with any specified through Annotated*.
