Subject [jira] [Created] (JXPATH-187) Possible endless loop in Namespace Resolving
Date Tue, 08 Dec 2015 15:22:10 GMT

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

             Summary: Possible endless loop in Namespace Resolving
                 Key: JXPATH-187
                 URL: https://issues.apache.org/jira/browse/JXPATH-187
             Project: Commons JXPath
          Issue Type: Bug
    Affects Versions: 1.3
            Reporter: Stefan Albrecht


When dealing with XML documents - org.w3c.dom - and when having a hierarchy of relative contexts,
then, when trying to resolve the namespace prefix for some namespace uri, an endless loop
is triggered.
This happens if
* the namespace is not programatically registered with JXPathContext
* the context used to resolve the namespace
** has a parent context
** and neither the context nor the parent have the namespace defined within the document

I attached a patch for org/apache/commons/jxpath/ri/NamespaceResolver.java
as well as a tar ball with a junit test and test files
