-------------------------------------

             Summary: Deleted entries from (Fine)AtomicMap reappear in subsequent transaction
                 Key: ISPN-5088
                 URL: https://issues.jboss.org/browse/ISPN-5088
             Project: Infinispan
          Issue Type: Bug
          Components: Core
    Affects Versions: 7.0.2.Final
            Reporter: Sanne Grinovero
            Priority: Critical


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:
