Deleted entries from (FineGrained)AtomicMap reappear in subsequent transaction

      Clear each AtomicMap via direct access (cache.get(key).clear()) before deleting it seems to work but is transactionally unsound most likely. Clear each AtomicMap via the atomic map retrieval proxy before deleting does not work.

      Clear each AtomicMap via direct access (cache.get(key).clear()) before deleting it seems to work but is transactionally unsound most likely. Clear each AtomicMap via the atomic map retrieval proxy before deleting does not work.

      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:

      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();

      Also applies apparently to a normal AtomicMap if using DIST_SYNC.

      I'm attaching a full test, which results in:
