Massive refactoring to exception handling. I'm trying to simplify things, but they are currently a little bit more complicated. I'll do another round shortly.
The main benefit of this change is that now all of our error handling flows through one class: Errors.java.
It takes care of
- managing the current source line,
- managing the current InjectionPoint
- building Messages
- toStrings
Because of this refactoring we now use almost exactly the same code for both ProvisionException and CreationException. The consequence of this is that ProvisionExceptions now include a full error report -- all of the classes injected. "Fail fast, but not too fast" now applies to Provide-time as well as Injector-create time.
I also made InjectionPoint into a public class in SPI. It replaces dependency. I like this change because "dependency" is a very abstract name, whereas InjectionPoint is very Guicey. Guice injects stuff. Dependencies are a consequence of this, but I like the API better exposing the core Guice abstractions directly.
This entire change needs further doc, simplification and cleanup. Todo.
