I assume we are leaning towards updating the file on save because updating while the user is typing would be very annoying. However, with https://code.visualstudio.com/docs/editor/codebasics#_save-auto-save , this could also make the feature just as annoying.

We might need to consider making some setting that automatically disables this functionality when auto-save is enabled.

This is now possible by ensuring the java.cleanup.actions setting includes the element : "renameFileToType" within the array value. It has also been set as the default option if a user has not overridden the setting with their own preferences.

Basically having

settings.json

...
"java.cleanup.actions": [
  "renameFileToType"
]
...
