I have a Java Web Start application calling remote Java EE 5 EJBs to load in data from a database. When the data is returned from the EJB to the client, I get the following exception. Looking it up online, it seems that everyone gets this exception and everyone has a different solution for it.

  • All of my entities (abstract or not) implement Serializable and have serialVersionUIDs.
  • The client and server are running the exact same JVM, 1.6.0_20
  • I am running GlassFish v2.1.1 with EclipseLink as the JPA provider.
  • Some of my entities use enums, but 1.6.0_20 doesn't have the enum serialization bug.
  • I initialized all lazy-loaded relationships server-side before passing them off to the client.

This person seems to think that this problem could be caused by having bi-directional @OneToMany/@ManyToOne relationships from an entity to itself, but I've had those in earlier versions of this program without a problem.

This is from the Java Web Start console:

Caveat: if you search the web, you'll see that this error message appears for several different problems (see the question for solutions I've tried that have failed), so this solution is not universal.

In this particular case, this appears to be caused by a regression introduced in EclipseLink version 1.1.2 and still present in versions 1.1.3, 1.2.0, and (skipping several versions) the latest one, 2.1.0. Reverting to EclipseLink 1.1.1 got rid of this error.

It only appeared in the (remote) Java Web Start client application -- the (local) web application (using the same entities) didn't encounter this problem. I'm still not sure exactly what in the program set off the bug.
