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

             Summary: XQuery support broken in Camel 2.18.x
                 Key: CAMEL-10653
                 URL: https://issues.apache.org/jira/browse/CAMEL-10653
             Project: Camel
          Issue Type: Bug
          Components: camel-saxon
    Affects Versions: 2.18.1, 2.18.0
            Reporter: Nikolay Voskresenskiy
         Attachments: camel-xquery-test.zip

The camel xquery support no longer works correctly as of 2.18.x

I identified two main issues so far:

# A java.lang.NullPointerException is thrown when exchange contains any null headers or properties:
{code}
java.lang.NullPointerException: External object cannot wrap a Java null
	at net.sf.saxon.value.ObjectValue.<init>(ObjectValue.java:55)
	at org.apache.camel.component.xquery.XQueryBuilder.addParameters(XQueryBuilder.java:640)
{code}
# An error in execution whenever a header or a property are referenced in the xquery as an external variable:
{code}
java.lang.AssertionError: Unknown event
	at net.sf.saxon.evpull.ComplexContentProcessor.advance(ComplexContentProcessor.java:198)
{code}

Attached is a maven project with junit test illustrating the issues.
