---------------------------------------
Summary: XQuery NPE going from saxon 9.5 to 9.7 (upgraded camel
from2.17.4-> 2.20.1)
Key: CAMEL-12081
URL: https://issues.apache.org/jira/browse/CAMEL-12081
Project: Camel
Issue Type: Bug
Components: camel-saxon
Affects Versions: 2.20.1
Environment: JDK 1.8.0_144. Windows 10 and Centos 7
Reporter: Riaan Annandale
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
Riaan
