I was able to reproduce a similar problem, but it was not the comments
that were causing it. It was happening to methods that were indented
(ie, defined within a class, as is always the case in Java).

Can you try adding a .gitattributes file at the root of your repository,
with the following contents:

*.java diff=java

After that, try running the command again, and see if that helps.

I suspect the default regex that tries to locate your function might not
be matching as well as it should, and does not handle indented function
definitions properly.

(More on what the .gitattributes file does:
