Hi,
my environment is Oracle DB server 11g, TopLink and Coherence.
I get a very strange exception when querying data already loaded into coherence cache:

I suppose that this is related to the load of the associations, The associations are defined using a Set and not a simple List as generally used.
Following an example:
private Set<PhysicalTermPoint> kidPhysicalTermPoint;
Any tip is more than expected because we are stuck with this problem for more than a week.
Thanks,
