[Radim Vansa (JIRA)]

Radim Vansa created ISPN-7526:
---------------------------------

             Summary: Write skew fires even if the previous value was not read
                 Key: ISPN-7526
                 URL: https://issues.jboss.org/browse/ISPN-7526
             Project: Infinispan
          Issue Type: Bug
          Components: Core, Transactions
    Affects Versions: 8.2.6.Final, 9.0.0.CR2
            Reporter: Radim Vansa
            Assignee: Radim Vansa


When the entry was overwritten without reading previous value and then we read it (this read is handled from the current context), write skew check is still applied and can fail, despite that it's unnecessary.

{code:java}
cache.put("k", "init");

tm.begin();
cache.getAdvancedCache().withFlags(Flag.IGNORE_RETURN_VALUES).put("k", "v1");
assertEquals("v1", cache.put("k", "v2"));
Transaction tx = tm.suspend();

assertEquals("init", cache.put("k", "other"));

tm.resume(tx);
tm.commit();
{code}
