Exception from annotation processing

[ggrell]

Any thoughts on what might be leading to this compile-time issue? Looking at Binding.java line 66, it's throwing the exception because I have a class marked as singleton but null binding key. I usually get error messages from the processor, but this time I'm in the middle of a big refactor when I started getting the error, so hard to say what code change might be leading to this.

An annotation processor threw an uncaught exception.
Consult the following stack trace for details.
