[infinispan-dev] getting stopped cache

[Ales Justin]

Or is this expected behavior? See below on why ...

I actually just saw this now -- I already had an existing CapeDwarf / GAE app deployed / present.
If I remove the app, the problem goes away.

Afaik, AS7 counts how many times EmbeddedCacheManager (ECM) is being used,
better, its AS7 service is depended on,
and if the number is 0, it then (re-)creates the ECM instance.

In my case -- with the app being present - ECM was never re-created when my tests were running.

So Cache::stop shouldn't remove cache from ECM?

Reading ECM::removeCache javadocs:
"but also deletes its contents both in memory and in any backing cache store."

Where I want my data to survive re-starts.
Will this ECM::removeCache also remove data for re-starts?
