The same JDK issues are present in the following tests as well
```
Testsuite: org.apache.nutch.protocol.httpclient.TestProtocolHttpClient
Tests run: 7, Failures: 7, Errors: 0, Skipped: 0, Time elapsed: 1.644 sec
```
and
```
Testsuite: org.apache.nutch.protocol.okhttp.TestProtocolOkHttp
Tests run: 2, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 1.827 sec
```
Additionally, I think we might want to address deprecation in the Nutch API. For example, when I execute a build, I see **59** javac deprecation notices in my build log. Maybe we could address that in a separate issue...
Thanks for anyone who can also review this patch.
