This is an easy gap to patch, but it seems there is either an explicit step missing or the syntax highlighting differs.
Prior to Listing 12.14 we hadn’t created the updateCrime() and addCrime() methods on CrimeRepository. This listing has us add the executor wrap around the Dao calls.
Either the entire 10 lines should be bold to show that code is being added or a Listing 12.13.2 is added to create the calls sans executor.
Not a problem, just an FYI if anyone is going through and wondering where those two calls came from.
