Well, the following will handle spaces just fine:

    $ find . -name '*.java' -print0 | xargs -0 grep -l 'Copyright'

This will actually be faster, since it will greatly minimize the
number of fork/exec pairs (your command line does a grep for *each*
file, whereas the find / xargs pipeline will do a *single* grep for
a bunch of files.) BTW, this isn't really a Cygwin-specific question,
rather a somewhat common Unix question.
