10 years ago This is a known issue with the kryo serializer, and fortunately is very rare, but difficult to reproduce. If you have definitive steps that reproduce the error, please send them to me so I can add them to the test suite.
Also, I've gotten reports from other users that bumping the kryo version resolves the issue. If you look at the pull requests on the repo, you'll find a contribution that bumps the kryo version number. I'm still in the process of vetting these before I pull them into a production version, but if you want to out that fix and let me know if it works for you, I'd appreciate it.

Upgrading to the kryo-serializers library, v0.26 seemed to resolve this. It's an easy work-around, but the less I have to manage up transitive dependencies, the better. :)
