> {color:#333333}When deploying the jar if all jar Classes are not loaded
> before a new deploy operation is issued Classes that were not loaded, when
> loaded, will use a different ClassLoader object. Therefore, all objects
> created by Classes with new ClassLoader will be incompatible with objects
> created by Classes with an old ClassLoader.{color}
> Fault is with JarDeployer Geode Class, deploy function, in which even if the
> deployed jar is the same a new ClassLoader object will be created and replace
> the old one.
> To reproduce the issue deploy some jar with an object declaration and a
> function that manages those objects. Then insert a few objects and deploy the
> same jar again without executing the function. Now when executing the
> function, function Class and its objects are created with a new ClassLoader
> and not castable to the object Class which uses the old ClassLoader.
> Expected error:
> {code:java}
> org.apache.geode.cache.execute.FunctionException:
> java.lang.ClassCastException: class {class.name} cannot be cast to class
> {class.name} ({class.name} is in unnamed module of loader
> java.net.URLClassLoader @5a57081e; {class.name} is in unnamed module of
> loader java.net.URLClassLoader @7efe7b87){code}
