Re: [eclipselink-users] ClassCastException when exeuting query
|
From looking at the stacktrace, there might be some code in your application like:
List<Event> newEvents = new ArrayList<>();
newEvents.add(...);
aTrip.setEvents(newEvents);
In this case, the error-condition might be avoided by a pattern like this:
List<Event> newEvents = new ArrayList<>();
newEvents.add(...);
aTrip.getEvents().clear();
aTrip.getEvents().addAll(newEvents);
It also might be worth a try to use the EclipseLink javaagent for dynamic weaving (ELUG #Using_Weaving).
Or if this all does not help, try to temporarily switch off the shared cache.
<property name="eclipselink.cache.shared.default" value="false" />
Please note that this is all pure speculation and might not be related to the actual bug.
HTH,

Do You know what causes the bug "to bite"?
Is it the combination of hints, we're using?
