@brianoliver said: Interestingly I could only reproduce this reliably when running on a later (unreleased) version of Coherence, but regardless it is an issue. This will be resolved in the next patch Coherence Incubator release (patch) 12.2.1 |

@brianoliver said: Are you using Coherence 12.1.2.0.1+? In 12.1.2.0.0 the class wasn't serializable. In 12.1.2.0.1+ it is. – Brian |

@brianoliver said: Can you attach your Cache Configuration file and possibly your CacheStore? – Brian |

@brianoliver said: If you change the in your cache store configuration to be , it should all work. The example you sent me works when I've done this (no longer fails). I'll update the documentation for this issue and raise an issue against the Coherence Product to make serializable. Thanks for you helps locating this issue. – Brian |

@brianoliver said: Instead what we'll do is "re-write" / "transform" uses of with in the Event Distribution configuration as schemes. This ensure backwards compatibility. |

I see an issue on even processor framework when I tested fail over cases, not sure if that due to any incorrect configuration. I ran 2 separate cache server jvm and did an update, it worked correctly. Killed one of the cache server JVMs, and tested the updated use case, it failed with following exception. Expectation is the other JVM needs to process that, but it throws the error as below
