Ales Justin commented on WELD-870: ---------------------------------- I've got two fix impls: (a) https://github.com/alesj/core/tree/weld-870 (b) https://github.com/alesj/core/tree/weld-870-lite When doing (a) I saw that I could just do (b). But (a) also adds some other things, similar to why we have @Dispose as Bean, so I didn't just throw it away.
