Wrong exception thrown when value missing in config

[John D. Ament]

I noticed the following logic:

                if (!hasValue) {
                    deploymentProblems.add(new
IllegalArgumentException("Missing converter for '" + key + "' from " +
injectionPoint));
                }

The problem isn't that the converter is missing, but that the value is
missing (and there's no default set).  Anyone against fixing the message?
