Review Comment:
I concur with this comment as well. Given that in other places in the code
base where the caching of IllegalArgumentException is being tested doesn't have
any explanation in the comments earthier I don't think the comment is needed
here as well. It wouldn't be a divergence from rest of the codebase.

I concur. This is much cleaner.
