    Description

      FULL PRODUCT VERSION :
      java version "1.6.0_23"
      Java(TM) SE Runtime Environment (build 1.6.0_23-b05)
      Java HotSpot(TM) 64-Bit Server VM (build 19.0-b09, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      Microsoft Windows [Version 6.1.7600]

      A DESCRIPTION OF THE PROBLEM :
      HttpURLConnection is unable to process non-standard HTTP methods like "PROPFIND" (WebDAV) or "PATCH".

      This is a major issue as PROPFIND and PATCH are not uncommon and gain more attenation with RESTful services and the rise of supporting APIs like JAX-RS.

      It makes no sense to restrict the set of possible methods, and it was never HTTP's intention to be restricted in that way (it is specifying just a base set of methods), so the restriction has to be removed ASAP.

      This is a showstopper for anybody in the need of connecting to WebDAV or PATCHable resources!

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      HttpURLConnection c = url.openConnection();
      c.setRequestMethod("PROPFIND");
      c.getInputStream();

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Will execute PROPFIND.
      ACTUAL -
       java.net.ProtocolException: Invalid HTTP method: PROPFIND
      at java.net.HttpURLConnection.setRequestMethod(Unknown Source)

      ERROR MESSAGES/STACK TRACES THAT OCCUR :
       java.net.ProtocolException: Invalid HTTP method: PROPFIND
      at java.net.HttpURLConnection.setRequestMethod(Unknown Source)

      REPRODUCIBILITY :
      This bug can be reproduced always.

      ---------- BEGIN SOURCE ----------
      see above
      ---------- END SOURCE ----------

      CUSTOMER SUBMITTED WORKAROUND :
      Using URLConnection and implement HTTP manually or use a third party HTTP library. Both breaks the WORA principle as whether PROPFIND works or not is dependent on something not told in the JavaDocs of HttpURLConnection!
