 Review comment:
   By coincidence, I was also working on this today. What I ended up doing was 
replacing a lot of these exceptions with their parent, 
`ReflectiveOperationException` to remove the redundancy, and to cover the 
additional ones thrown by the `getDeclaredConstructor().getInstance()` pattern.
