Don't worry, I did not read it that way.

> After a {{FineGrainedAtomicMap}} containing some data is deleted in a transaction, but then in the same transaction it's re-created, the next transaction will be able to read the original data which it contained.
> Some pseudocode:
> {code}tx1.start();
> am = AtomicMapLookup.getFineGrainedAtomicMap( cache, cacheKey, true );
> am.put(k1, v1);
> tx1.commit()
> tx2.start();
> am = AtomicMapLookup.getFineGrainedAtomicMap( cache, cacheKey, true );
> am.put(k3, v3);
> AtomicMapLookup.removeAtomicMap( cache, cacheKey );
> am = AtomicMapLookup.getFineGrainedAtomicMap( cache, cacheKey, true );
> am.put(k2,v2);
> tx2.commit()
> tx3.start();
> am = AtomicMapLookup.getFineGrainedAtomicMap( cache, cacheKey, true );
> am.contains(k1) == false; // FAILS!
> tx3.commit();{code}
> Also applies apparently to a normal AtomicMap if using DIST_SYNC.
> I'm attaching a full test, which results in:
> {noformat}
