[infinispan-issues] [JBoss JIRA] (ISPN-5088) Deleted entries from (FineGrained)AtomicMap reappear in subsequent transaction

    [ https://issues.jboss.org/browse/ISPN-5088?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13028765#comment-13028765 ] 

Sanne Grinovero commented on ISPN-5088:
---------------------------------------

Most tests in OGM are single-node non clustered. Some tests use clustering, but I guess it's possible that something changed in Infinispan so that what used to be a the primary node in those tests isn't primary anymore in Infinispan 7.
This certainly didn't happen in our limited tests on Infinispan 6, but it's possible we had too few tests.

> 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}
