Marco--

I've got a PR at https://github.com/apache/jena/pull/471. Until we hear from 
Andy, could you perhaps try cloning that PR/branch and trying the new code out? 
If that is not a reasonable piece of work for you, no problem, but it would 
help greatly in validating that we've found and fixed the problem.
