Subject Re: Running compatibility and upgrade tests using jdk9+
Date Thu, 11 Oct 2018 17:26:08 GMT
I think we should run some sort of backwards-compatibility tests between
Java 8 and Java 9/11+. We need testing of Geode (both old and current
versions) on older JVMs talking to Geode on newer JVMs. (for example, what
if Java built-in serialization changes in a way that breaks our code
somehow?)
