> Key: OAK-4658
> URL: https://issues.apache.org/jira/browse/OAK-4658
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: query
> Reporter: Thomas Mueller
> Assignee: Thomas Mueller
> Fix For: 1.5.8, 1.4.7
>
>
> Outer join queries with a condition of "name(joinSelector) = 'x'" or
> "localname(joinSelector) = 'x'" can result in a NullPointerException. This is
> because the code doesn't take the "no-match" case into account (that the
> joined selector doesn't have a node). Example queries:
> {noformat}
> select a.[jcr:path] from [nt:base] as a
> left outer join [nt:base] as b on ischildnode(b, a)
> where name(b) = 'b'
> select a.[jcr:path] from [nt:base] as a
> left outer join [nt:base] as b on ischildnode(b, a)
> where localname(b) = 'b'
> {noformat}
