> The DocumentNodeStore revision GC may cause a NPE in a reader thread when the GC deletes
documents currently accessed by the reader. The {{docChildrenCache}} is invalidated in {{VersionGarbageCollector.collectDeletedDocuments()}}
after documents are removed in the DocumentStore. The NPE may occur if removed documents are
access in between.
