I'm seeing this, too, but I'm not sure semantic-ia-complete-symbol is causing it. Malabar never seems to start. (I don't know how to get an emacs debug trace like yours)

I ran C-u M-x run-groovy, then opened a Java file. I get no syntax coloring and the message from the title.

EDIT: Trying to open a Java file results in this message in Messages:

file-name-nondirectory: Wrong type argument: stringp, nil

I also have this. Seems to be caused by javap output buffer which has no file. I worked around it by wrapping the body of malabar-mode-body in when:

(defun malabar-mode-body ()
  (when (buffer-file-name (current-buffer))
  ...

Thanks. I will get that looked at. I am in the middle of a large refactor to support gradle as well as maven so things are a bit broken but I will get this in as soon as I can. Do a pull request and I will get it added.
