>> The code change refactors classes that have a `SuppressWarnings("removal")` annotation that covers more than 50KB of code. The big annotation is often quite faraway from the actual deprecated API usage it is suppressing, and with the annotation covering too big a portion it's easy to call other deprecated methods without being noticed.
>> The code change shows some common solutions to avoid such too wide annotations:
>> 1. Extract calls into a method and add annotation on that method
>> 2. Assign the return value of a deprecated method call to a new local variable and add annotation on the declaration, and then assign that value to the original l-value if not void. The local variable will be called `tmp` if later reassigned or `dummy` if it will be discarded.
>> 3. Put declaration and assignment into a single statement if possible.
>> 4. Rewrite code to achieve #3 above.
>> I'll add a copyright year update commit before integration.
