问题：使用rest-assured测试rest service, 遇到“415 Unsupported Media Type”
Appserver的log：
[6/18/15 21:35:31:961 CDT] 0000001d org.apache.wink.server.internal.RequestProcessor I The following error occurred during the invocation of the handlers chain: WebApplicationException (415 - Unsupported Media Type) with message 'null' while processing DELETE request sent to http://......
但是在脚本里是设了Content-Type的，这是控制台打出的log:
Request method: DELETE
Request path: http://......
Proxy: <none>
Request params: <none>
Query params: _informat=json
Form params: <none>

百思不得其解，最后在rest-assured的问题列表里发现了这个 Issue 362: Content-Type seems to work in console out, but it's not really working (https://code.google.com/p/rest-assured/issues/detail?id=362)
把rest-assured从2.3.2升级到2.4.0，问题解决。
