Details

      • 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

    Description

      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:

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
