WARNING [com.squareup.okhttp.OkHttpClient] (OkHttp ConnectionPool) A connection to https://api.github.com/ was leaked. Did you forget to close a response body?

I am using version 1.116. I sometimes see this warning message in my server log, there is no real occurrence pattern. I am not sure why that happened, but it seems it relates to bad network connection.

In my code, I have a static GitHub instance and use it periodically to communicate with Github.

    protected static GitHub github;

...
// create the github instance from initialization like below 
...

    github = new GitHubBuilder()
            .withOAuthToken(config.getPassword(), config.getUsername())
            .withConnector(new OkHttpConnector(new OkUrlFactory(new OkHttpClient().setCache(cache))))
            .build();

I can see similar message mentioned in a previous pull request #346 on Feb 23, 2017 trying to ignore the warning from okhttp.

Does this really a harmful messages ? How should I prevent this in github-api since I don’t use okhttp directly.

Thank you.

Thanks, I have tried with okhttp3, the warning seems gone.

@soul2zimate Try switching to okhttp3 v3.14.x. It should be a drop in replacement if all you’re doing is using URLConnection. I’m deprecating support for 2.x.
