> RBackendHandler is swallowing general exceptions in handleMethodCall which
> makes it impossible to debug certain issues that happen when doing an
> invokeJava call.
> In my case this was the following error
> java.lang.IllegalAccessException: Class
> org.apache.spark.api.r.RBackendHandler can not access a member of class with
> modifiers "public final"
> The getCause message that is written back was basically blank.
