Unexpected end of ZLIB input stream

[Vasyl Vaskul]

I have the following exception while using browsermob:

I am using testng run tests in parallel, selenium grid with browsermob, jdk 1.7

Thanks in advance.

Can you give me a bit more of a test case? I tried this test case and it passes fine:

public class MailingListIssuesTest extends DummyServerTest {

    @Test

    public void zlibIssue() throws IOException, InterruptedException {

        proxy.setCaptureContent(true);

        proxy.newHar("Test");

        HttpGet get = new HttpGet("http://static.ak.fbcdn.net/rsrc.php/v2/yk/r/_6PVaUm7dAE.js");

        HttpResponse response = client.execute(get);

        IOUtils.readFully(response.getEntity().getContent());

        Assert.assertEquals(200, response.getStatusLine().getStatusCode());

        Har har = proxy.getHar();

        Assert.assertEquals(200, har.getLog().getEntries().get(0).getResponse().getStatus());

    }

…

}

Note: this is a modification of MailingListIssuesTest.java in the project. I did NOT, however, check this test in as I prefer to avoid hitting public URLs that look like they can change regularly, such as this one.

I am using Selenium Interpreter to play selenium tests using RemoteWebDriver with browsermob proxy.

Server running browsermob proxy and server launching browser with proxy are different servers.
