-----------------------------------

             Summary: XPath: queries starting with "//" are not always 
converted correctly
                 Key: OAK-4376
                 URL: https://issues.apache.org/jira/browse/OAK-4376
             Project: Jackrabbit Oak
          Issue Type: Bug
            Reporter: Thomas Mueller
            Assignee: Thomas Mueller
             Fix For: 1.5.3


XPath queries starting with "//" are not always converted to the expected SQL-2 
query. Examples:

{noformat}
//element(*, oak:QueryIndexDefinition)/*
select [jcr:path], [jcr:score], * from [oak:QueryIndexDefinition] as a

//element(*, oak:QueryIndexDefinition)//*
select [jcr:path], [jcr:score], * from [oak:QueryIndexDefinition] as a
{noformat}

This is wrong. Instead, a join should be used.
