Somehow DB got into this situation again (identical stack traces). I end-up removing (commenting out) @Version field from PSLBase class and now it works (without any changes to DB).
I think it points quite conclusively that something is not right with the way @Version field influence enhanced code. I will be more then happy to admit that I am doing something wrong, but I would like to know what exactly I am doing wrong.
