BrowserMobProxy newHar throws exception

[toberoo]

I didn't have this issue last week, but when I try to call newHar I get an exception. I tried running it a few ways, in intellij, just the jar, ect.. but here are some scenarios I tried.

BrowserMobProxy proxy = new BrowserMobProxyServer(); proxy.start(0);

    // get the Selenium proxy object
    Proxy seleniumProxy = ClientUtil.createSeleniumProxy(proxy);

    // configure it as a desired capability
    DesiredCapabilities capabilities = new DesiredCapabilities();
    capabilities.setCapability(CapabilityType.PROXY, seleniumProxy);

    // start the browser up
    WebDriver driver = new FirefoxDriver(capabilities);

    // enable more detailed HAR capture, if desired (see CaptureType for the complete list)
    proxy.enableHarCaptureTypes(CaptureType.REQUEST_CONTENT, CaptureType.RESPONSE_CONTENT);

    // create a new HAR with the label "yahoo.com"
    proxy.newHar("yahoo.com");

    // open yahoo.com
    driver.get("http://yahoo.com");

    // get the HAR data
    Har har = proxy.getHar();

Even removing selenium from the equation throws an error:
BrowserMobProxy proxy = new BrowserMobProxyServer(); proxy.start(0); proxy.enableHarCaptureTypes(CaptureType.REQUEST_CONTENT, CaptureType.RESPONSE_CONTENT); proxy.newHar("yahoo.com"); Har har = proxy.getHar();

If I uncomment proxy.newHar("yahoo.com") everything runs, minus the fact that I can't get a HAR. Here is the stack trace for the error. I appreciate any help as I've been struggling to figure out the issue:

Encountered the same problem

What version of BMP are you using? The most recent versions don't rely on the external calls to populate user agent data.

I do want to get rid of ua-detector though, since it's not supported and horribly out-of-date. Unfortunately there's not a great replacement.

On Android 6.0

I finally removed uadetector, though it didn't make it into the 2.1.3 release. @misakuo or @toberoo - can you try with the latest code from master?

It seems to be working now, thanks.
