Matt Whipple updated LUCENE-7926: --------------------------------- Description: {{org.apache.lucene.queryparser.flexible.core.nodes.QueryNodeImplL67}} casts the argument to {{QueryNodeImpl}} although the rest of the code is written against the {{QueryNode}} interface. This blows up in cases where a non-inheriting implementation is passed (such as using a wrapper/decorator class). The relevant {{setParent}} method does not exist on the interface, so the most backwards compatible short term fix would be to wrap the cast in a conditional to ensure it is safe.
