Could you raise a JIRA for this?  And if you have a patch, submit that as well?

There's another problem, with model.listStatements(s,p,o,null), which behaves as
model.listStatements(s,p,o,"") (when o != null)

I created one JIRA for both (and proposed a patch)

Thank - now fixed in SVN in the build tonight of
Jena version 2.10.0-SNAPSHOT

I'll do - but I have no time before Friday.

As far as I can see, e.g. the code style in that area, it's been that way since 
the year dot, so Friday is just fine!

Bizarre.  The code does not filter as you (and I) expected.

Could you raise a JIRA for this?  And if you have a patch, submit that as well?

While it is technically a change to the formal API, your expectation seems 
entirely intuitive.

Small issue of whether case should matter and whether a filter of "en" matches 
"en-UK" (c.f. SPARQL LANGMATCHES) but for the API, at least exact match seems reasonable 
to me.
