CWE: CWE-611 \u2014 Improper Restriction of XML External Entity Reference
The product processes an XML document that can contain XML entities with URIs that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output.

Code:
	public IClasspathEntry decodeClasspathEntry(String encodedEntry) {

		try {
			if (encodedEntry == null) return null;
			StringReader reader = new StringReader(encodedEntry);
			Element node;

			try {
				DocumentBuilder parser =
					DocumentBuilderFactory.newInstance().newDocumentBuilder();
				node = parser.parse(new InputSource(reader)).getDocumentElement();
			} catch (SAXException | ParserConfigurationException e) {
				return null;
			} finally {
				reader.close();
			}

			if (!node.getNodeName().equalsIgnoreCase(ClasspathEntry.TAG_CLASSPATHENTRY)
					|| node.getNodeType() != Node.ELEMENT_NODE) {
				return null;
			}
			return ClasspathEntry.elementDecode(node, this, null/*not interested in unknown elements*/);
		} catch (IOException e) {
			// bad format
			return null;
