Error in scala-mode

[wedens]

When I open some scala file that contains "TODO", I get this error:

Debugger entered--Lisp error: (args-out-of-range 0 21)
  remove-list-of-text-properties(0 21 (display face font-lock-multiline))
  font-lock-default-unfontify-region(0 21)
  font-lock-unfontify-region(0 21)
  font-lock-default-fontify-region(0 2 nil)
  font-lock-fontify-region(0 2 nil)

  apply(run-hooks (change-major-mode-after-body-hook prog-mode-hook scala-mode-hook))
  run-mode-hooks(scala-mode-hook)
  scala-mode()

If I reopen the same file, it opens without any errors.

I can reproduce it with .scala file that contains just new RuntimeException("TODO") // TODO line

I cannot reproduce that. Did you try reproducing it starting from emacs -Q?

[wedens]

It doesn't happen every time the file is opened. I may need to reopen the file or restart emacs several times to reproduce the issue.

Did you try reproducing it starting from emacs -Q?

No. I've tried to reproduce it with as much of my configuration disabled as possible and the error still occurs.

This might be an issue in your setup (including additional packages), or it might be an issue with scala-mode. It might also be a hl-todo issue, but that is much less likely.

I am closing this. You probably have no choice but to really start from emacs -Q. If you provide more information, then I might be able to help but as it stands I would have to resort to guessing.

Here's a guess: We just had a similar issue with tex-mode: #52. Something in your setup might make the same mistake and the fix might be similar as well.
