Since I upgraded my JDE a few weeks ago, after I start up Xemacs and load a Java source file, I get the following annoying warning in another frame everytime I do something in the Java buffer:
(1) (warning/warning) Error caught in `font-lock-pre-idle-hook': (wrong-type-argument stringp nil) After a "while" in that session, however, this warning eventually stops appearing. I don't know how long it takes, or what I do to make it go away, but I just don't see it anymore after that point. Until it gets to that point, it is really annoying, as I can't view two buffers at the same time without it wiping out the other every time I move the cursor. I'd like to either figure out how to make Xemacs completely ignore this error, or figure out how I can get more information about what is happening so I can resolve this. I tried the simple-minded approach of running "edebug-defun" in "font-lock-pre-idle-hook", but that immediately crashed Xemacs. I guess that was a "don't do that".
