HttpService cause http connection leak

[ciferliu]

application log

okhttp3.OkHttpClient - A connection to http://localhost:8545/ was leaked. Did you forget to close a response body? To see where this was allocated, set the OkHttpClient logger level to FINE: Logger.getLogger(OkHttpClient.class.getName()).setLevel(Level.FINE);

==============
okhttp3 java doc
okhttp3.ResponseBody

A one-shot stream from the origin server to the client application with the raw bytes of the response body. Each response body is supported by an active connection to the webserver. This imposes both obligations and limits on the client application.

The response body must be closed.
Each response body is backed by a limited resource like a socket (live network responses) or an open file (for cached responses). Failing to close the response body will leak resources and may ultimately cause the application to slow down or crash.

Please provide information to reproduce

This is caused when an error is returned (okhttp throws an error if it's not 2xx) from the rpc endpoint.

This is still an open issue. The change I made didn't solve the issue and was reverted.

This was auto-closed from the merge.
