Unreachable code in JAXBAttachmentUnmarshaller
----------------------------------------------
Key: AXIS2-4463
URL: https://issues.apache.org/jira/browse/AXIS2-4463
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Components: jaxws
Reporter: Andreas Veithen
Priority: Minor
While reviewing some code, I noticed that
org.apache.axis2.datasource.jaxb.JAXBAttachmentUnmarshaller contains
unreachable code. There are two places where the following if statement is used:
if (xmlStreamReader instanceof OMXMLStreamReader) {
...
}
"xmlStreamReader" is an attribute of JAXBAttachmentUnmarshaller, but this
attribute is never initialized and remains null (this is obviously a bug; see
code in the constructor). Since "null instanceof X" is always false, the code
inside the if statement is unreachable.
Since this code is related to XOP/MTOM processing, I'm wondering how it is
possible that MTOM actually works in JAX-WS (does it?). Also it would be
interesting to analyze why this issue doesn't trigger any test failure.
