[seam-dev] Overriding annotated types and the SPI

[Gavin King]

Pete, there are allowed to be two AnnotatedTypes for the same Java class.

Even with this fix, you would have an error, as you now have two identical classes which Weld will discover beans for. You need to veto the built in annotated type (otherwise you end up *adding* an existing annotated type, not replacing it).

Does anyone have any idea what could be causing this? It looks like the bean deployment process is overriding my user supplied type level metadata.
