NullPointerException in ChildContext
------------------------------------
Key: JXPATH-113
URL: https://issues.apache.org/jira/browse/JXPATH-113
Project: Commons JXPath
Issue Type: Bug
Reporter: Michele Vivoda
Priority: Minor
In ChildContext I get a NullPointerException, the error appears in method
prepare()
iterator = (startFromParentLocation ? parent.getParent() :
parent).childIterator(nodeTest,
reverse, startFromParentLocation ? parent : null);
should be changed in my opinion to
final NodePointer actualParent = startFromParentLocation ? parent.getParent() :
parent;
iterator = actualParent==null ? null :
actualParent.childIterator(nodeTest,
reverse, startFromParentLocation ? parent : null);
The tests triggering the error are testIssue172_CountFollowingSiblingNode and
testIssue172_CountPrecedingSiblingNode
