I have modified {{Partition.installMergeView()}} to compute the digest explicitly and it fixed {{CrashedNodeDuringConflictResolutionTest}}. Unfortunately it also caused {{*TxPartitionAndMergeDuring*Test.testPrimaryOwnerIsolatedPartitionWithDiscard()}} to fail every time:

The problem seems to be that the majority partition installs a stable topology and completes the transaction before the merge. The test is passing without the merge digest because the {{TxCompletionNotificationCommand}} is retransmitted by the originator to the minority partition, but with the digest set properly that no longer happens:

> The partition handling tests use {{BasePartitionHandlingTest.Partition.installMergeView(view1, view2)}} to install the merge view without waiting for {{MERGE3}} to run, making them much faster. Unfortunately, the implementation is incorrect: {{GMS.installView(view)}} only works for regular views, merge views need to be installed with {{GMS.installView(mergeView, digest)}}.
> The result is that the nodes that got isolated from the coordinator request the retransmission of all the {{NAKACK2}} messages (including view updates) since the cluster first started. The isolated nodes cannot install the merge view until they deliver all the older messages (even without knowing whether they're OOB or not). But if {{STABLE}} ran and cleared a range of messages already, the retransmission request cannot be satisfied, so the view updates will never be delivered.
> This is easily reproducible in {{CrashedNodeDuringConflictResolutionTest}} if we add a delay before updating the topology in {{StateConsumerImpl}}. The test installs the merge view manually, but then kills NodeC and expects the cluster to install the new view automatically. NodeD can't install the new view because it's waiting for earlier messages from NodeA:
