I'm getting this error trying to load a turtles file (.ttl) into a new tdb
database.
Here is the traceback:

The code in question is:
Dataset ds = TDBFactory.createDataset( tdbDest ) ; // tdbDest is a String
Model model = ds.getDefaultModel() ;
RDFReader rdfRdr = model.getReader( "TTL" );
File f = new File( ttlDir, fn ); // ttlDir is a File, fn is a String
InputStream dataStream = new FileInputStream( f );
rdfRdr.read( model, dataStream, null ); // <-- this is where the error
occurs
dataStream.close();
Is there a way to find out where in the file the error occurred? Is this
indicative of a specific problem?
My ttl file has many lines with \unnnn UTF-8 coded entries, if that has any
impact.
Thanks
