Ah, thanks for that. So, since forever.

In one of the bug reports that I mentioned upthread a fellow
compiled his library using maven and javac, then uploaded to
maven central, created a maven project in Eclipse and would
not compile due to a spurious \u00?? in his source!!
So even far flung language features sometime can cause bug bites.

I mention in my post to JDT this from Java VM Spec 14:

Module names may be drawn from the entire Unicode codespace, subject to 
the following constraints:

• A module name must not contain any code point in the range
' \u0000 ' to ' \u001F ' inclusive.

But no mention in JLS as far as I can tell?

I wonder if this will be an inconsistency waiting to bite?
