--------------------------------------
Summary: .NET: Transaction fails with multiple write-through caches
Key: IGNITE-5786
URL:
https://issues.apache.org/jira/browse/IGNITE-5786 Project: Ignite
Issue Type: Bug
Components: platforms
Affects Versions: 1.6
Reporter: Pavel Tupitsyn
Assignee: Pavel Tupitsyn
Fix For: 2.2
To reproduce: create two caches with {{WriteThrough=true}} and some {{CacheStore}} (implementation can be empty).
Attempt to update both caches within a transaction:
{code}
using (var tx = ignite.GetTransactions().TxStart())
{
cache1.Put(1, 1);
cache2.Put(1, 1);
tx.Commit();
}
{code}
Exception occurs:
{code}
(err) Failed to notify listener: o.a.i.i.processors.cache.distributed.near.GridNearTxLocal$

Explanation:
* Cache stores share same session within a transaction
* Session in Java is uses to store .NET session handle, so both stores have the same .NET session (which is good: consistent with Java)
* Each store calls sessionEnd, so session gets released multiple times - this causes HandleRegistry exception
Current unit test uses Spring XML with shared {{PlatformDotNetCacheStoreFactory}}, which caches created store instance for some reason, so the bug is hidden, since both caches use the same store instance.
