> 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.
