Trying to move a project from test into production phase, I have started to get internal exceptions when working on large data sets:
java.util.concurrent.ExecutionException: com.objectdb.o.InternalException: Unexpected internal exception
....
Caused by: com.objectdb.o.InternalException: Unexpected internal exception at com.objectdb.o.WSM.U6(WSM.java:118) at com.objectdb.o.QRR.g(QRR.java:244) at com.objectdb.o.QRR.f(QRR.java:153) at com.objectdb.jdo.JdoQuery.execute0(JdoQuery.java:811) at com.objectdb.jdo.JdoQuery.execute(JdoQuery.java:720)
I can imagine how frustrating such internal exceptions must be to sort out. Is there any more information I can provide?
