After checking in more detail, I got to a point where most was replaced by built-in JDK classes. However, there are some references left in com.hp.hpl.jena.iri.impl.AbsLexer and one in com.hp.hpl.jena.rdf.arp.impl.CharacterModel which I don't know how to resolve due to lack of Unicode experiences nor enough time resources that I can spend on that. If you want I can create patches and send them to you - unfinished work, though. I also tried to simply comment the remaining references (they all seem to be kind of syntax checks) and run the JUnit tests, but that apparently failed.
