Description

Hi, 

I'm using Olingo odata2 to partial update odata service. (http://services.odata.org/(S(3pkdpur1gd4on3iid50ckdcs))/V2/OData/OData.svc/)

and I get below error: 

• Failed to update entity because: Invalid HTTP method: PATCH

• Invalid HTTP method: PATCH Context: java.net.ProtocolException: Invalid HTTP method: PATCH
  at java.net.HttpURLConnection.setRequestMethod(HttpURLConnection.java:440

Looking at code of java.net.HttpURLConnection.setRequestMethod(), the method does not  contains PATCH, see: 

/* valid HTTP methods */
private static final String[] methods =

{ "GET", "POST", "HEAD", "OPTIONS", "PUT", "DELETE", "TRACE" }

;

Any solution or workaround on this? 

Regards,

Wendy
