Gang,
I am working on Google AppEngine support again, and implementing both
a MapEntityStore as well as a native one (to be able to compare and
provide choice).
Now, looking at the version() in DefaultEntityState, it seems that
version() is intended for migration support. BUT,
ConcurrentModificationCheckConcern assumes it revolves around
"instance versions". This must be a fairly obscure and important bug,
but I just want to make sure before I tackle it.
Any comments?
version() in DefaultEntityState is used for instance versions. There's
nothing in DES for application version. That is done entirely by the
MapEntityStore when saving the state (line 192).
