> Key: ISPN-4444
> URL: https://issues.jboss.org/browse/ISPN-4444
> Project: Infinispan
> Issue Type: Bug
> Components: Core, State Transfer
> Affects Versions: 7.0.0.Alpha4
> Reporter: Dan Berindei
> Assignee: Pedro Ruivo
> Priority: Critical
> Fix For: 7.1.0.Alpha1
>
>
> When state transfer ends and each node receives a CH_UPDATE command from the coordinator, it first installs the new topology and then it starts invalidating entries it no longer owns.
> However, there are two cases when the node can still read its stale values:
> 1. If L1 is enabled, it will look in the local DataContainer first, regardless of the key's location.
> 2. If L1 is disabled, but the key was removed on the new owners, the node will still look up the key in the local DataContainer after receiving a null response.
> The problem can be reproduced with {{TxReadAfterLosingOwnershipTest}} and its subclasses, by replacing the {{operation.update(cache(1));}} line with {{operation.update(cache(0));}}
