Deleted entries from (FineGrained)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 Assignee: William Burns Priority: Critical Labels: for_OGM Attachments: Testcase-ISPN-5088.patch 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.
