Not possible to get server config over REST

The following request http://localhost:11222//rest/v2/server/config with GET method shows error eventhough there is no exception in the logs.

java.lang.IllegalArgumentException: application/xml; q=0.9

This happens only if the request is sent over browser. If I am sending request of CURL command from cmd line, then the config is shown properly. I guess it happens because wrong headers are sent over browser, wdyt?
