[cdi-dev] calling 'equals' on a proxy?

Hi folks!

There is a problem still in the chain which is a bit more trickier. It's about equals() on contextual references.

If the 'other' instance which gets compared with is a proxy as well, then we would first need to 'unpack' it and pass the underlying contextual instance into the comparison implementation. Otherwise accessing private fields from the 'other' will actually only hit the proxy, and not the 'real' target.

But otherwise it should work fine. 


1.) Should we specify this? 

2.) What is the expected behaviour? 

3.) Do we like to specify equals() for beans at all?
4.) Is there some established behaviour in other frameworks which heavily uses proxies?
5.) Should we at least specify that 'non portable behaviour results'?
