"Add throws declaration" formats entire file

When you use the "Add throws declaration" it formats the entire file instead of just adding the throws clause to the current function.

Environment

• Operating System: Windows 10
• JDK version: openjdk 11.0.4 2019-07-16
• Visual Studio Code version: 1.38.1
• Java extension version: 0.50.0

Steps To Reproduce

1. Create a java file start writing some code and have it not match the default formatter. (like indenting case under a switch)

2. write a function that calls a function that throws a checked exception (like CompletableFuture.get)

3. Use the suggestion to add throws declarations to the current function.

Current Result

Throws declarations are added but the entire file gets formatted

Expected Result

only the throws declarations should be added to the current function and the rest of the file is untouched.

Empieza reproduciendo la sugerencia Add throws declaration en un archivo Java con un formato distinto del predeterminado y una llamada como CompletableFuture.get. Sigue las rutas de la sugerencia y del formateador para determinar por qué se activa el formateo; se considera terminado cuando solo la función actual obtiene su throws declaration y el resto del archivo permanece sin cambios.
