I have a unidirectional one-to-many that is causing problems. It is mapped using a join table (since it's unidirectional). The instance variable in the entity is typed as a Set. I have verified that the equals and hashCode methods of the entity whose instances are stored in that Set are well-behaved (i.e., the state on which they are based is not mutated after insertion into the Set, etc.). And I have inspected the Set of the offending entity at runtime and I don't see any duplicates.|
The thing is....
When running with classes that have been statically woven I get the error shown below. When I turn weaving off the error no longer occurs.
Just wondering if anyone has an idea why that would be?
