[jira] [Updated] (OAK-6294) The "missing" node cache value breaks
the DNStore#applyChanges
[ https://issues.apache.org/jira/browse/OAK-6294?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tomek Rękawek updated OAK-6294:
-------------------------------
Description:
In the {{DocumentNodeStore#nodeCache}}, the special object {{missing}} is being used to mark the node entries that don't exists in the repository.
This object should be unwrapped to {{null}} every time we call {{nodeCache#getIfPresent()}} method. It's not the case in the {{applyChanges()}} method - as a result, we may get a NPE (since the {{missing.getLastRev() == null}}).
