Certain restful web service based apps make use of DELETE requests with request bodies. Those apps work fine in major browsers but not in WebView. The problem is, WebView uses HttpURLConnection for all HTTP exchanges, and HttpURLConnection explicitly disallows request entities in DELETE requests. The latter is actually a bug in the HttpURLConnection implementation, see http://monaco.sfbay.sun.com/detail.jsf?cr=7157360. This Jira issue fully depends on that bug.
Jira is an example of an app that uses DELETE requests with request bodies. When the user clicks the "Watching" link on an issue page to delete himself from the list of watchers, the page sends a DELETE request to the server along with some data in the request body. Currently, what happens is WebView simply avoids sending the request body to the server, due to the above limitation and the change introduced by RT-20551. Luckily, the request body does not seem to have any significance to the server in this case, so the whole thing works out fine. However, the problem still remains, as other applications may rely on the request body and fail if the request body does not get transmitted to the server.
