Description

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

//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

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