"Failed to serialize instance" of Set problem

Hi,

I'm trying to persists objects defined as follows:

@Entity
@Inheritance(strategy = InheritanceType.SINGLE_TABLE)
public abstract class AbstractContainer {
...

  @OneToMany(fetch = FetchType.LAZY, mappedBy="parent")
  private Set<AbstractContainer> abstractContainers = com.google.common.collect.Sets.newIdentityHashSet();
}

Got the following exception:

com.objectdb.o.UserException: Failed to serialize instance of com.google.common.collect.Sets$SetFromMap - field xxx.AbstractContainer.abstractContainers
at com.objectdb.o.MSG.d(MSG.java:74)

What do I wrong?

Maybe the set contains objects that cannot be serialized.

Check the full stack trace, including nested exceptions, in the log file.

Hi support,

Yes, stack trace shows ObjectDB tries to serialize the collection using ordinary Java serialization ignoring the @OneToMany reference :-(

Build 2.4.7_06 should add support of Google collections. Please try it.

Looks like it works in 2.4.7_06
