             Summary: Better support for versionable nodes without version histories
                 Key: OAK-3844
                 URL: https://issues.apache.org/jira/browse/OAK-3844
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: upgrade
    Affects Versions: 1.3.13
            Reporter: Tomek Rękawek
             Fix For: 1.4


One of the customers reported following exception that has been thrown during the migration:

{noformat}
Caused by: java.lang.IllegalStateException: This builder does not exist: 95a5253f-d37b-4e88-a4b4-0721530344fc
	at com.google.common.base.Preconditions.checkState(Preconditions.java:150)

	at org.apache.jackrabbit.oak.upgrade.RepositoryUpgrade.copy(RepositoryUpgrade.java:486)
{noformat}

It seems that the node with reported UUID has primary type inheriting from {{mix:versionable}}, but there is no appropriate version history in the version storage.

Obviously this means that there's something wrong with the repository. However, I think that the migration process shouldn't fail in this case but log a warning and proceed.
