Get timeout when testClearFormData.This case test clear form data in website.

case code:
    public void testClearFormData() throws Throwable {
        if (!NullWebViewUtils.isWebViewAvailable()) {
            return;
        }
        try {
            startWebServer(false);
            WebSettings settings = mOnUiThread.getSettings();
            settings.setDatabaseEnabled(true);
            settings.setJavaScriptEnabled(true);
            WebViewDatabase webViewDatabase = WebViewDatabase.getInstance(getActivity());
            webViewDatabase.clearFormData();
            final String url = mWebServer.getAssetUrl(TestHtmlConstants.LOGIN_FORM_URL);
            mOnUiThread.loadUrlAndWaitForCompletion(url);
            new PollingCheck(TEST_TIMEOUT) {
                @Override
                public boolean check() {
                    return !WebViewDatabase.getInstance(getActivity()).hasFormData();
                }
            }.run();

            // Click submit (using JS, rather than simulated key presses, to avoid IME
            // inconsistencies).
            mOnUiThread.evaluateJavascript("document.getElementsByName('submit')[0].click()", null);
            new PollingCheck(TEST_TIMEOUT) {
                @Override
                public boolean check() {
                    return WebViewDatabase.getInstance(getActivity()).hasFormData();
                }
            }.run();
        } finally {
            WebViewDatabase.getInstance(getActivity()).clearFormData();
        }
    }

Earlier log exist socket closed.
12-24 20:04:53.305 19725 19776 W CtsTestServer: java.net.SocketException: Socket closed

We don't know why CtsTestServer throw SocketException.

why v54 fail,v55 pass?

thanks
