   > It looks like the test is expecting the the call to `recover()` to fail 
and if it doesn't, the test will fail via the call to `fail()`. But in this 
case, the `fail()` statement will be caught as a `Throwable` and **not** cause 
the test to fail when reached, Functionally, the whole try catch block does 
nothing more than call `recover()`. I'm not certain im interpreting this 
correctly but if I am, I'm not sure how to handle this case.
   
   Yeah, ErrorProne is correct. `fail()`, like all the JUnit assertions, 
triggers an `AssertionError` that is caught and reported. We shouldn't be 
catching `Throwable` here, because it will also catch and ignore that 
`AssertionError`. We should only catch `Exception`, at most. We need to figure 
out which exception is expected, and use `assertThrows` with that directly like 
you've done with the others.
