After I save a file, LSP updates the file but does not refresh the buffer

[joe-humphreys]

Describe the bug
Every time I save a Java file, LSP's save hooks run, which usually results in the file being changed on disk. However, the buffer where I am visiting the file does not get refreshed. So when I go to make further changes, I get a message <filename> changed on disk; really edit the buffer? (y, n, r or C-h). Effectively, that means every time I save, I have to wait a moment and then hit 'r' before doing further edits, which is very distracting.

To Reproduce

1. Open a java file.
2. Go to any line with code on it and add a few spaces at the beginning of the line.
3. Save the file
4. Begin typing

Expected behavior
If a background process changes a file I've got open in a buffer, the changes should just show up immediately in the buffer, without prompting me to revert.

It seems do not caused by lsp-java. I can't find a hook named lsp-save-hook.
did other file have this error eithor when you save them? If so check your emacs self setting maybe help .
