JDE args-out-of-range problem

[vedm]

When I open a Jana file in JDE mode I get very often this error when
Emacs fontifies the buffer:

Debugger entered--Lisp error: (args-out-of-range 5 5)
  match-beginning(5)
  (or (match-beginning 5) (match-end 1))
  (goto-char (or (match-beginning 5) (match-end 1)))
  eval((goto-char (or (match-beginning 5) (match-end 1))))
  font-lock-fontify-keywords-region(504 1085 nil)
  font-lock-default-fontify-region(504 1011 nil)
