StaxSource: Bug in parse() method for character streams
-------------------------------------------------------
Key: SM-498
URL: https://issues.apache.org/activemq/browse/SM-498
Project: ServiceMix
Issue Type: Bug
Components: servicemix-core
Affects Versions: incubation
Reporter: Holger Bethke
We are playing around with servicemix and the jsr181 component when we run into
a strange problem. We are sending a SOAP request to a defined Service by the
jsr181 component with a long parameter value inside. The strange thing is that
the parameter value won't be send correctly to the NMR. Instead the value is
repeated several times for the first 1024 characters. We took a look in your
source files and found the responsible location for that behaviour. It looks
like there's a bug in the class org.apache.servicemix.jbi.jaxp.StaxSource, line
66:
protected void parse() throws SAXException {
try {
contentHandler.startDocument();
while (true) {
switch (streamReader.getEventType()) {
case XMLStreamConstants.ATTRIBUTE:
case XMLStreamConstants.CDATA:
break;
case XMLStreamConstants.CHARACTERS:
if (!streamReader.isWhiteSpace()) {
for (int textLength = streamReader.getTextLength();
textLength > 0; textLength -= chars.length) {
int l = Math.min(textLength, chars.length);
==> streamReader.getTextCharacters(0, chars, 0, l);
contentHandler.characters(chars, 0, l);
}
}
break;
The first parameter of the method XMLStreamReader.getTextCharacters() defines
the sourceStart (index of the first character in the source array to copy)
parameter. In your implementation this value is 0 every time. That's the
reason why we run into our problem...
