WebView doesn't show JSAlert on Lollipop devices

Question

It wasn't showing JSAlert on any devices. And then I set a WebChromeClient:

webView.setWebChromeClient(new WebChromeClient() {

            @Override
            public boolean onJsAlert(WebView view, String url, String message,
                    JsResult result) {
                return super.onJsAlert(view, url, message, result);
            }

            @Override
            public boolean onJsPrompt(WebView view, String url, String message,
                    String defaultValue, JsPromptResult result) {
                return super.onJsPrompt(view, url, message, defaultValue,
                        result);
            }

        });

Now it works fine on all pre-Lollipop devices. And doesn't show any alert on Lollipop devices.

Logcat says "Cannot create a dialog, the WebView context is not an Activity".

There is a bug introduced in version 40 of WebView, and is fixed in version 42.
