> Key: CAY-2801
> URL: https://issues.apache.org/jira/browse/CAY-2801
> Project: Cayenne
> Issue Type: Bug
> Components: Core Library
> Affects Versions: 4.2.RC2
> Reporter: Nikita Timofeev
> Assignee: Nikita Timofeev
> Priority: Blocker
> Fix For: 4.2, 5.0.M1

>
> {{IdGenerationMarker}} class uses parent id hash as a data source for the
> equals() method.
> This could cause severe problems like data missing in the commit in case of
> the hash collision in two ids and usage of the
> {{OpIdFactory.ReplacementAwareObjectId}} id implementation.
> There's already a commit that is part of CAY-2777 fix, that significantly
> reduces risk of this problem:
