Subject [jira] [Created] (AXIOM-393) Premature END_DOCUMENT event generated by OMStAXWrapper
Date Sat, 15 Oct 2011 15:17:11 GMT
Premature END_DOCUMENT event generated by OMStAXWrapper
-------------------------------------------------------

                 Key: AXIOM-393
                 URL: https://issues.apache.org/jira/browse/AXIOM-393
             Project: Axiom
          Issue Type: Bug
          Components: DOOM, LLOM
    Affects Versions: 1.2.12
            Reporter: Andreas Veithen
            Assignee: Andreas Veithen
            Priority: Minor
             Fix For: 1.2.13


In some cases, the XMLStreamReader returned by OMContainer#getXMLStreamReader generates a
premature END_DOCUMENT event.

This occurs when all of the following conditions are met:

1. Caching is turned off.
2. The subtree contains elements that have the same name as the element on which getXMLStreamReader
is invoked (example:. <element><element><element/><element/></element></element>).
3. The subtree is partially built.

The root cause can be traced back to an incorrect fix for AXIOM-151 which introduced the following
code in OMStAXWrapper (see r552397):

//this is a potential place for bugs
//we have to test if the root node of this parser
//has the same name for this test
if (currentEvent == START_ELEMENT &&
        (parser.getLocalName().equals(((OMElement)rootNode).getLocalName()))) {
    ++depth;
} else if (currentEvent == END_ELEMENT   &&
       (parser.getLocalName().equals(((OMElement)rootNode).getLocalName())) ) {          
                           
    --depth;
    if (depth < 0) {
        state = COMPLETED;
    }
}
