This is also a problem with Xerces 2.2.1.
It seems only to happen when the path has spaces in it for me. 

There is an alternative which does work with Xerces 2.2.1 which is to use an
Entity resolver.

When setting up the doc builder call:
docbuilder.setEntityResolver(new XMLEntityResolver(DOCTYPE_PUBLICID,
"/path/to/log4j.dtd"));

The XMLEntityResolver class looks like this:
public class XMLEntityResolver implements EntityResolver {
    
    String m_dtdId;
    String m_dtdResource;
    
    /**
     * Construct a new XMLEntityResolver
     * @param id the public Id that this entity resolver will match
     * @paramm resource the path to the resource to load the DTD from
     */
    public XMLEntityResolver(String id, String resource) {
        m_dtdId = id;
        m_dtdResource = resource;
    }
    
    public InputSource resolveEntity(String publicId, String systemId) throws
SAXException, IOException {
        if (publicId == null) {return null; }
        if ( publicId.equals(m_dtdId) ) {
            InputStream input = this.getClass().getResourceAsStream(m_dtdResource);
            InputSource isrc = new InputSource(input);
            return isrc;
        } else {
            return null;
        }
    }
    
}

HTH
Andi.
