             Summary: Inserting into cache with indexing fails for XA transactions
                 Key: ISPN-4569
                 URL: https://issues.jboss.org/browse/ISPN-4569
             Project: Infinispan
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Embedded Querying, Transactions
    Affects Versions: 7.0.0.Alpha5
            Reporter: Radim Vansa
            Assignee: Sanne Grinovero


If I setup XA transactions in {{ClusteredQueryDslConditionsTest}} using
{code}
cacheCfg.transaction().transactionMode(TransactionMode.TRANSACTIONAL).useSynchronization(false);
{code}

the test fails. The reason is in deadlock while updating {{ScopedKey}} in  __cluster_registry_cache__ : It seems that on originator we create transaction with modified inserted key and the {{ScopedKey}} for inserted class, and send it in two prepare commands to the other node. In the {{ScopedKey}}-prepare, the lock is acquired, but the regular prepare on the other node does not see it (it is not committed yet) and also tries to update this {{ScopedKey}} in  __cluster_registry_cache__ . This fails with lock timeout, as the commit is waiting on the regular prepare to finish.
