------------------------------------
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.
