One with a hello message with message separator and newline and one with only message separator. But problem is that I get no exception in the test without the newline. Any ideas what I am missing or how I can re-create the issue?

In your test, an EOF takes the place of the otherwise expected EOL and
makes it work.

As for the problem overall, in my view you definitely shouldn't be using
readLine() here. You should be reading with read(char[]) and keep doing
so until you encounter the separator.
