Hi openjpa-users list, just to answer my question myself... or give some tipps...
The problem might be a problem with the openjpa-enhancement. I tried the same procedure without the enhancement and it worked. As a "test", I tried eclipse-link and had no problems with the same source-code as before (using the runtime-weaving of eclipse). As I think, the problem might have something to do with the enhanced-field "protected transient boolean pcVersionInit;" but I haven't looked into details...
