Yep. I am using that with Fuseki patched according to:
https://issues.apache.org/jira/browse/JENA-63

> But your  tdbloader -version returns 0.8.11 ...

Yes.

> How did you install your tdbloader?

Here:
http://openjena.org/wiki/TDB/Installation
http://openjena.org/wiki/TDB/Commands

Or, just checkout and package as you now know how to do and set the
TDBROOT and PATH environment variable as suggested here:
http://openjena.org/wiki/TDB/Commands

> Do I run tdbloader in a wrong way with a "java -cp

No, it's not a wrong way (it's a different way and, by the way, very
useful and easy for Fuseki users). I usually do that as well.

There must be a bug in the 
org.apache.jena:jena-tdb:jar:0.9.0-incubating-SNAPSHOT.
I've just published a new SNAPSHOT and I does not seem to have the problem:
https://repository.apache.org/content/repositories/snapshots/org/apache/jena/jena-tdb/0.9.0-incubating-SNAPSHOT/

So, problem fixed.

To avoid this sort of problem in future, I am going to set up a -nightly job
in Jenkins (https://builds.apache.org/view/G-L/view/Jena/) to publish TDB
SNAPSHOTs in the Apache Maven snapshot repository, every night.

Hopefully we are at the end of this long thread.

Please, Jérôme, confirm you are happy!

Paolo
