> Very good reproduces in IgniteCachePartitionedNearDisabledPrimaryNodeFailureRecoveryTest.testOptimisticPrimaryAndOriginatingNodeFailureRecovery1.
> Approximate scenario:
> - there are several nodes in topology
> - node A starts tx prepare
> - one node fails, exchange is started
> - all servers except node A finishes 'waitPartitionRelease()' and coordinator waits for
node A
> - node A also fails, but it was able to send prepare request and it will be processed
> - since node A failed others nodes can finish exchange, without waiting for tx completion
> Note: to increase possibility change nodes start order in IgniteCacheAbstractTest:
> {noformat}
>     protected void startGrids() throws Exception {
>         int cnt = gridCount();
>         assert cnt >= 1 : "At least one grid must be started";
>         //startGridsMultiThreaded(cnt);
>         startGrid(0);
>         startGrid(1);
>         startGrid(3);
>         startGrid(2);
>         awaitPartitionMapExchange();
>     }
> {noformat}
> It seems one possible solution: exchange should wait when all messages from failed node
are processed.
