Yes, and generally for any non-String type where instances of that
type are created from a String value the same issue can arise.
I had recently considered that Jersey should attempt to obtain all
injected values. If one or more exceptions are thrown when obtaining
the values that all exceptions should be reported, being wrapped
around an uber-exception. Then an ExceptionMapper could be utilized.

Yes, we originally thought that the application would be responsible
for validating. But, there are potentially some things we might be
able to do, like using AOP as we have discussed.
