Exception messages missing useful information: "Injection point has unsatisfied/ambiguous dependencies
------------------------------------------------------------------------------------------------------

                 Key: WELD-542
                 URL: https://jira.jboss.org/browse/WELD-542
             Project: Weld
          Issue Type: Bug
          Components: Resolution (Typesafe and by Name)
    Affects Versions: 1.0.1.Final
            Reporter: Lincoln Baxter III


I feel like the following exception message is missing some very useful information (e.g, the type of the object that could not be satisfied;) I don't want to have to look at the injection point in order to see what it couldn't find. Also, I have to skim over a few words before I get the information that really tells me what's going on. "Unsatisfied dependencies" should be the primary focus of the message.

WELD-001408 Injection point has unsatisfied dependencies.  Injection point:  field org.jboss.seam.faces.status.MessagesAdapter.context;  Qualifiers:  [@javax.enterprise.inject.Default()]

The message should probably look something like this, instead:

WELD-001408 Unsatisfied dependencies for type [org.jboss.seam.international.status.Messages] at injection point [field] [org.jboss.seam.faces.status.MessagesAdapter.context]. Qualifiers:  [@javax.enterprise.inject.Default()]

This way, I immediately know that I have unsatisfied dependencies, and the type that cannot be resolved. From there, I can see where the type is being requested and its qualifiers.

I'd like to see the same thing done for the Ambiguous dependencies exception message:

Existing:

 Injection point has ambiguous dependencies. Injection point: field
   org.jboss.seam.faces.status.MessagesAdapter.context; Qualifiers: [@javax.enterprise.inject.Default()]; Possible dependencies: [org.jboss.seam.international.status.Messages1, org.jboss.seam.international.status.Messages2]

Proposed:

Ambiguous dependencies for type [org.jboss.seam.international.status.Messages] at injection point [field] [org.jboss.seam.faces.status.MessagesAdapter.context]. Qualifiers: [@javax.enterprise.inject.Default()]; Possible dependencies: [org.jboss.seam.international.status.Messages1, org.jboss.seam.international.status.Messages2]
