[jira] [Created] (LUCENE-7926) Unsafe type cast in flexible parser QueryNodeImpl

Matt Whipple created LUCENE-7926:
------------------------------------

             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.
