script type
Grep every calls to the function under the cursor with your grepprg.
...closely organized like jreplace script is .. @see Vim wiki

1 - Starts with a :normal mA  .. AS A GLOBAL MARK [A] .. you can jump back to as a return point.

2 - The resulting list will be inserted as a multi-line comment in the current buffer .. you can undo at will:
        /* CALLERS::
        src/file.js:485      caller_f:493:     callee_f(args);
        src/file.java:485  caller_f:493:     callee_f(args);
3 - Let you navigate the grep quickfix resulting list.

- Currently tuned up to catch .js and .java calling function def lines into the list third field.
- And you will figure out how to get more by adjusting the F_callers:fdef pattern.

- USES [A global mark] as a call return point
...(there are 2 calls to [A mark] you can adjust to use another mark :normal mA and :normal 'A

- USES [b register] to store the resulting multi-line-comment
...(so as you can undo the insertion .. but keep the results handy)
...(there are 3 setreg(b) calls you can adjust to use another register

- USES [q register] to store the generated :grep call
...(so you can use @q to edit and call it yourself later)
...( :nnoremap Q   @q .. may help )
install details
- put the file where you put your other scripts (it has no dependency)
- then map something to source it.
...mine is:
:nnoremap <esc><c-s-down>   :so ~/VIM/scripts/jcallers.vim<cr><cr>
