Hi Uli, I am able to reproduce a similar error when I use a TreeMap instead of a LinkedHashMap for RoadDef objects in TableA. I think the problem was introduced with the merge of the unicode branch (r3076) which introduced the new encText field in Label and a possible text==null . @Steve: I am not sure what to do here. A method like City.getName() should probably used the getEncText() method if getText() returns null? But getEncText() returns a char[] while getText() returns a String, so that seems to be inefficient :-( Gerd

Last night this error happened again at the same spot. The remedy is still the same: Run only one thread or declare the method synchronized.
I still think, something is not right there...
