Description

When using the method DatatypeConverter.printBase64Binary a NullPointerException occurs.

java.lang.NullPointerException
javax.xml.bind.DatatypeConverter.printBase64Binary(DatatypeConverter.java:173)
Servlet.doGet(Servlet.java:17)
javax.servlet.http.HttpServlet.service(HttpServlet.java:621)
javax.servlet.http.HttpServlet.service(HttpServlet.java:722)

The following example servlet will throw the NPE:

@WebServlet("/npe")
public class Servlet extends HttpServlet {

@Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException

{ String s = DatatypeConverter.printBase64Binary("TomEE & JAXB!".getBytes(StandardCharsets.UTF_8)); resp.getWriter().write(s); }

}

A workaround is to remove the JAXB jars from the lib & endorsed directories. My application seems to work fine but I have no idea what (hidden) problems this might cause.
