-----------------------------------------
since security-conscious users will employ SSL we should close this ticket
> Geode put may result in inconsistent cache without SSL if network packets are
> tampered with

> Key: GEODE-4748
> URL: https://issues.apache.org/jira/browse/GEODE-4748
> Project: Geode
> Issue Type: Bug
> Components: membership, serialization
> Affects Versions: 1.0.0-incubating, 1.1.0, 1.1.1, 1.2.0, 1.3.0, 1.2.1,
> 1.4.0
> Reporter: Vadim Lotarev

> Geode cache became inconsistent in case if networking and serialization
> problems occur at commit time. How to reproduce:
> # create any simple _replicated_ region
> # run two nodes
> # put some value in the region (within a transaction or not)
> # execute query on both nodes to check that the same value is returned (I
> used JMX for that)
> # emulate somehow temporary networking or serialization error (throw
> IOException from toData() or use [clumsy|https://jagt.github.io/clumsy/] to
> emulate network interruption)
> # repeat [#3], exception should occur
> # repeat [#4] - you should see different values on different nodes
> It looks like errors occurred after {{TXState.applyChanges}} produce
> inconsistency - it is impossible to rollback applied local changes what leads
> to the state where local cache contains changed data but other node(s) old
> data (before changes made in transaction).
> To me, consistency is a key property for the systems like Geode so I would
> consider this bug as a critical one.
