NPE in HttpServletRequestImpl.getLocalAddr()

XMLWordPrintable

      • Set up WildFly 12 behind a reverse proxy,
      • Enable proxy-address-forwarding attribute on the http-listener,
      • Ensure the RP sends X-Forwarded-Host header,
      • the application calls down to getLocalAddr

      If the following circumstances are all present:

      • WildFly 12 sits behind a reverse proxy,
      • The proxy-address-forwarding attribute is set to true for the http-listener,
      • The reverse proxy sends X-Forwarded-Host header,
      • and there is a call to getLocalAddr

      The following NPE can be seen:

      Caused by: java.lang.NullPointerException
