This is a bug in CDI 1.0, that we didn't have Interceptor.intercept() rethrow checked exceptions to be compatible with the interceptors spec.

As a result, it is difficult to put portable extensions that use the SPI into one of categories defined by the document.

I think we can count it as this. But let me check with Bill.
C. Wrapper implementations of the specification. These provide classes that implement interfaces defined in the specification but they do so by simply wrapping a vendor implementation and adding some additional value. Examples are framework developers and resource adapter developers.
