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

             Summary: xpath throws NPE if body is null when camel-saxon is used 
as JAXP implementation
                 Key: CAMEL-14155
                 URL: https://issues.apache.org/jira/browse/CAMEL-14155
             Project: Camel
          Issue Type: Bug
          Components: came-core
            Reporter: Luigi De Masi


despite [XPath API spec| 
https://docs.oracle.com/javase/8/docs/api/javax/xml/xpath/XPathExpression.html#evaluate-java.lang.Object-javax.xml.namespace.QName-]
 states:

{quote}If a null value is provided for item, an empty document will be used for 
the context\{quote}

saxon, starting from 9.6, they decided to ignore it and throw NPE if the node 
is null, from [saxon 
javadoc|https://www.saxonica.com/html/documentation9.8/javadoc/net/sf/saxon/xpath/XPathExpressionImpl.html#evaluate-java.lang.Object-javax.xml.namespace.QName-]:

{quote} Contrary to the interface specification, Saxon does not supply an empty 
document when the value is null. This is because XPath 2.0 allows the context 
item to be "absent" (null). So Saxon executes the XPath expression with the 
context item undefined.\{quote}
