[OJB-developers] Extent aware cache

[Michal K. <mkl...@ya...>]

Hi,
I just found a serious bug in my application
and it looks like the problem lays in ObjectCacheDefaultImpl.
Situation looks like this:

interface A {
...
}

class AImpl implements A {
...
}

class B {
  A aReference;
}

class C {
  AImpl aImplReference; //points to the same instance as B.aReference
}

After reading objects B and C should be:
B.aReference == C.aImplReference.

But it is not!!!
The problem is that cache is not aware of extents so:
cache(B.aReference) puts <"A{x}", B.aReference> into the hashtable and
lookup(C.aImplReference) looks for "AImpl{x}" and returns null.

Regards,
Michal
