I've written an ANTLRv3-based tool to do this kind of thing with
ActionScript, and might give you some ideas:

I think that the JaxMeJS may do this for Java, to some extent (and it's
parser is ANTLR-based) but I'm not sure how pretty the resulting code
is, as I've never tried round-tripping with that lib, only straight code
generation,

However, if you are modifying Java files, and doing it in Eclipse too, I
suspect you'd be best off using the Eclipse JDT platform's inherent support
for Java code manipulation (not that I know which API's you need to look
at though ;)
