false for a pdx of class com.springone.austin.vursys.battle.model.Vote_",
instead.
The Stack Trace is:

{code}
The Apache Geode code did *not* properly consider that there was simply no
public, no-arg constructor on the application domain type (e.g. {{Vote}})! Of
course, after adding a public, no-arg constructor to the application domain
type, everything works as expected!
The error and message is very misleading!
