cached objects in the object context?

I have a couple of different systems modifying the database my cayenne =
code is talking to. Every now and then I see behaviour that I think says =
that something is being cached between database searches even though I =
create a new context before each search:
ObjectContext context =3D cayenne.newContext();   (cayenne is a =
ServerRuntime built like at the end of this message)

Even though I'm creating a new context before the search, could the =
server runtime that the context is built from be caching objects? If so, =
should I wipe the cache before the search? Or is there a way to make =
sure it doesn't work with a cache?

thanks,
Rob
