[ http://issues.apache.org/jira/browse/AXIS2-818?page=all ]
Ajith Harshana Ranabahu resolved AXIS2-818.
-------------------------------------------
Resolution: Fixed
Changed the implementation of the wrapper to fix this issue. Basically the
intention of the wrapper is to produce a fake START_DOCUMENT event if the real
parser rests at the START_ELEMENT event. Now the parser returns the
START_DOCUMENT if the state of the internal parser has not been touched but
never throws the START_DOCUMENT from the next method.

> Project: Apache Axis 2.0 (Axis2)
> Issue Type: Bug
> Components: core
> Affects Versions: 1.0
> Reporter: Raymond Feng
> Assigned To: Ajith Harshana Ranabahu
>
> If StreamWrapper is used to wrap a XMLStreamReader positioned at
> START_ELEMENT, then it will produce START_DOCUMENT events twice.
> Assuming StreamWrapper wrapper = new StreamingWrapper(realReader);
> 1) wrapper.getEventType() returns START_DOCUMENT
> 2) wrapper.next() still returns START_DOCUMENT by the logic in code below.
> (in this case, state==STATE_INIT && realReader.getEventType() ==
> START_ELEMENT)
> public int next() throws XMLStreamException {
> prevState = state;
> int returnEvent = -1;
> switch (state) {
> case STATE_INIT:
> if (realReader.getEventType() == START_DOCUMENT) {
> state = STATE_SWITCHED;
> returnEvent = realReader.getEventType();
> } else {
> state = STATE_SWITCH_AT_NEXT;
> returnEvent = START_DOCUMENT;
> }
> break;
> ...
> }
