Good catch!
As Adam pointed out, you're using the read() method with a wrong second
argument, i.e. when you use
model.read(String url,
String base)
the second argument is the base IRI. What you probably want is to use
the read() method with three arguments having the signature
model.read(String url,
String base,
String lang)
and the language beeing the third argument:
model.read("http://example.com/ExampleOntology.owl";, null, "TURTLE");
See Javadoc [1] for more information.
