I also tried to avoid setting prefixes and move on with what I need to do.
But, I hit another strange problem:
Exception in thread "main" java.lang.NoSuchMethodError:

What I am doing is just adding a model to another one (backed-up by TDB):
model.add(m)
No pressure, but I'd like to understand if I am doing something wrong
or if others experience similar issues.
Thanks,
Paolo
PS:
I am going to try using the latest/stable TDB release now...
