The code appears to be fine. It takes a bunch of hashes and returns all the keys that they have in common. In your example data there are no keys in common, so it correctly returns nothing. Your modification makes it return all the keys in any of the hashes, probably not what is wanted.

update: I am assuming that inter implies intersection here. I don't have a copy of the Camel third edition personally.

update 2: ... and that assumption is correct.
