An assertion here indicates that invariants have been violated (a problem in our own code which should never happen), not that bad/unexpected bytes were received. If that happens (assert fired), we want to know about it. Assertions are typically enabled in testing (they are when running JDK tests) but not in production.

yes - otherwise you would have to read the logs in order to notice the stack trace there, because simply dropping the packet will typically not make the test to fail (it did not in our case, hence the reason it went unnoticed).
