Re: flymake integration for the eclipse java compiler

Hi James,

Can you try getting the latest flymake.el from CVS, commenting out the
line that looks like this:
  (flymake-reformat-err-line-patterns-from-compile-el
compilation-error-regexp-alist-alist))

and uncommenting the previous line, ie the line that looks like this:

   ;; compilation-error-regexp-alist)
