This certainly suggests an incompatibility with the Jena that you are 
using. However, the error seems to be about the field individualAsThingP 
in com.hp.hpl.jena.vocabulary.ReasonerVocabulary class which (AFAIT) is 
unchanged since at least Jena 2.3. So you might have an earlier Jena in 
your classpath or some other classpath problem.
