Bug#851557: maven-repo-helper: Fails to parse <Xlint:unchecked/>

[Emmanuel Bourg]

This issue also occurs with jakarta-activation 2.0:

  SEVERE: An error occured when processing the pom file ./activation/pom.xml
  javax.xml.stream.XMLStreamException: ParseError at [row,col]:[76,17]

I tried disabling namespace awareness in POMReader with:

    protected final XMLInputFactory factory = XMLInputFactory.newInstance();
    {
        factory.setProperty(XMLInputFactory.IS_NAMESPACE_AWARE, Boolean.FALSE);
    }

But this doesn't work, the parser then throws an exception on namespace declarations.

The solution is probably to switch to the same XML parser used by Maven (xpp3?).
