> In the case of an HARegion, AbstractRegionMap.initialImagePut deserializes the value to set the haContainer. Normally, that value is a wrapped by a VMCachedDeserializable, and deserializing it replaces it in the VMCachedDeserializable. With -Dgemfire.PREFER_SERIALIZED=true, the value is wrapped by a PreferBytesCachedDeserializable and deserializing it creates a copy of the value. It doesn't replace it in the PreferBytesCachedDeserializable.
> So, in this case, the haContainer is being set on a copy of the value, not the value itself. It has no effect, and the value put into the HARegion has no haContainer.
> This is not really an issue until this member needs to provide an initial image for another member.
> At that time, a NullPointerException like this occurs:
> {noformat}
