Watermarking a java source file?

This struck a thought:

You could do like map makers of old: introduce a specific, small,
different bug in each version. You're gambling they don't find it and
fix it--they would all have to be such that it doesn't adversely
affect your algorithm in an obvious way (the bugs *have* to be in your
secret sauce--since that's what you're worried about leaking).

Again, may not be possible, but like Levi says, w/o changing the
meaning of the code (and behavior), any other changes to the source
code will not be detectable.
