Hi Peter, Jason, Joe,

Thanks for the pointers. I have missed the use of serialPersistentFields (thanks to Peter for calling this out). I read the javadoc and serialization spec but that didn't come clearly to me. It'd be good to include an example in the javadoc (will file a JBS issue).

W.r.t. the package-private API to set the cause in EIIE [1], yes it's needed and it's done in webrev.01. Let me redo the readObject/writeObject part and send a new webrev.

Hi Mandy,

This what we were doing in the past and has examples of removing fields with expected tests: http://mail.openjdk.java.net/pipermail/core-libs-dev/2018-February/051339.html http://mail.openjdk.java.net/pipermail/core-libs-dev/2013-June/017594.html > However, this case is a little different because it actually disallows subsequent initCause. I would assume that will get tricky if you deserialize the old binary form in a newer JDK because we would have to jump through some hoops to update null to the cause exception. Jason
