Description

CDI relies on EL but at the same time goes against what's the EL specification says. For instance, CDI makes it possible to have names with "." (dot) but it's forbidden in EL because the dot is used to navigate the tree and find sub nodes.

An implementation now has to create a bean manager based Resolver that has specific rules for CDI beans. The trick is that the EL Context can be populated but other means than just CDI, so "a.b" can lead to ambiguous resolutions.

Shouldn't we get ride of this edge case in CDI only?

Research direction

Start by reviewing the CDI bean-manager-based Resolver and how the EL Context is populated for CDI beans. Compare CDI's support for dotted names with the EL specification's navigation rules and consider the ambiguity when other sources populate the context. Done means reaching and documenting a clear specification decision.
