             Summary: Unsafe type cast in flexible parser QueryNodeImpl
                 Key: LUCENE-7926
                 URL: https://issues.apache.org/jira/browse/LUCENE-7926
             Project: Lucene - Core
          Issue Type: Bug
            Reporter: Matt Whipple
            Priority: Trivial


{{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.
