The offset attribute that you want to adjust is arglist-cont-nonempty.  I
prefer the default of c-lineup-arglist (which is basically a function
pointer to a defun from cc-align.el), but you'd like to set that to 4.

I was able to guess that from examining the above and comparing it to the
source of cc-vars.el, but there's a better way.  Consider the code below:

myFancyFunction("a big long argument which is going to make me insert a " +
                "string concatenation ... hopefully javac is smart");

Position your cursor at the beginning of the second line, on or near the
word "string".  Invoke the interactive function c-set-offset by typing M-x,
then c-set-offset, and hitting return.  You'll be prompted for the "Synatic
symbol to change", with Emacs' best guess filled in.  Following the above
instructions, that should be arglist-cont-nonempty.  If so, hit enter.  If
not, delete what Emacs filled in for ya and press tab twice to see the list
of possible completions.  After selecting arglist-cont-nonempty, you'll be
prompted for the offset you'd like.  AFAICT, this can be any real number, a
symbol (which could be a variable, function pointer, etc.), or the "+"  
character for your default offset (c-basic-offset, which I usually set to
4).  Sounds like you want to use c-basic-offset here, which you can type in
directly (without completion) or use the special + character for (this is
what I would do).

Is that what happened to me...?  ;P
