I don't think there's any code in CC Mode to re-indent auto-filled stuff
(apart from comments).  It's one of these things that "nobody" will ever
really need (Hah!), and nobody can be bothered to code.  The variable
c-ignore-auto-fill seems more like an emergency kludge than a fully
worked out facility.

If you think about it, auto-fill with reindentation would be complicated -
The Java code could be filled, then reindented, causing it to spill over
the right margin, requiring re-filling, then reindentation, .....  It
would probably end up looking like an Outlook-Express Usenet posting.  :-(

You could always reindent the code with C-M-\ or C-M-q or something.  But
that will ruin the 75 column limit.  :-(  There probably isn't a good
solution to this (other than to enhance CC Mode).  Sorry.
