Dmitry Volodin commented on CAMEL-12081:
----------------------------------------
This issue is related to saxon and not related to camel-saxon component
implementation.
I've checked provided test on top of the Camel 2.21.0-SNAPSHOT version and it's
working correctly.
I will create a separate PR to update saxon to the version 9.8.0-6 on top of
the Camel 2.20.2.
> XQuery NPE going from saxon 9.5 to 9.7 (upgraded camel from2.17.4-> 2.20.1)

> Hi guys
> I think saxon went to 9.7 in camel 2.18 (could be 19). Anyway, I used the
> latest to illustrate my problem (2.20.1 at the time of writing)
> I have a routes that receive XML payloads which I then transform via
> xqueries. Inside these I use local functions for readability (read: it's the
> first thing I tried when solving my problem and it worked).
> Since saxon went to 9.7 I get a null pointer exception when an xquery
> containing a local function tries to process the XML.
> To demonstrate this, I have made a GitHub project:
> [https://github.com/rannandale/xqueryIssue]
> In the project I use two xqueries to transform the same source.
> - One uses an inline for loop:
> <o>
> <variables>{for $v in /root/Data return $v/Name}</variables>
> </o>
> - One uses the local function style:
> declare function local:loopMe($nodes)
> {
> for $node in $nodes
> return
> <variables>{$node/*:Name}</variables>
> };
> <o>
> {local:loopMe(/root/Data)}
> </o>
> The latter is the one that returns the NPE.
> I know I could probably go refactor all my xqueries to match the inline
> style, but I figured I'd see if there is an issue here other than PEBKAC.
> They also get quite complex, so it's quite a bit of work.
> Thanks guys
