CAMEL-10817: Prevent duplicated xmlns namespace prefix when dumping model
XML
----
> dumpModelAsXml can return invalid XML namespace xmlns:xmlns
> -----------------------------------------------------------
>
> Key: CAMEL-10817
> URL: https://issues.apache.org/jira/browse/CAMEL-10817
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 2.18.0
> Reporter: James Netherton
> Assignee: James Netherton
> Priority: Minor
>
> Seems I introduced a
> [bug|https://github.com/apache/camel/blob/master/camel-core/src/main/java/org/apache/camel/model/ModelHelper.java#L99]
> when implementing CAMEL-10509.
> If we're processing a namespace prefix of 'xmlns' then obviously we should
> not prefix it with the same value. But currently this is allowed and a
> namespace prefix of 'xmlns:xmlns' is added to the {{<routes>}} element. This
> can mean that the output from {{ModelHelper.dumpModelAsXml}} is invalid.
> However, I can only reproduce the problem on Karaf where the routes use xpath
> expressions. Some how with other platforms & scenarios the 'xmlns:xmlns'
> value is being ignored and never makes it into the {{dumpModelAsXml}} output.
