The ability to launch the browser outside the main Thread

[TyutterinYakov]

Good afternoon! Earlier, you sent an implementation option.

    public static void main(String[] args) throws Exception {
        ChromiumBrowser.earlyInit();
        final IndependentBrowser browser = (IndependentBrowser) ChromiumBrowser.windowless(URL);

        // Wait for browser creation, then schedule screenshot in separate thread
        browser.isCreated().thenRun(() -> {
            Executors.newSingleThreadScheduledExecutor().schedule(() -> {
                try {
                    //.....
                    byte[] screenshotBase64 = browser.captureScreenshot().join();
                    byte[] pngBytes = Base64.getDecoder().decode(screenshotBase64);

                    Path screenshotPath = Paths.get("screenshot.png").toAbsolutePath();
                    Files.write(screenshotPath, pngBytes);

                    System.out.println("Screenshot saved to: " + screenshotPath);
                    browser.close();
                } catch (Exception e) {
                    System.err.println("Screenshot failed: " + e.getMessage());
                    e.printStackTrace();
                    browser.close();
                }
            }, 5, TimeUnit.SECONDS); // Wait 5 seconds for page load
        });
        ChromiumBrowser.startBrowsers(); //The main thread is completely blocked and when calling the close method browser.close(), nothing happens.
        //It will never be fulfilled...(((
    }

But its problem is that it leads to the shutdown of the application after performing all the actions, and I would like it to continue after closing the browser, but even when calling the close method of the browser, execution does not continue.

Hi @TyutterinYakov , I have verified the problem in your example. Currently, the browser closes correctly, but the CEF loop does not terminate because it requires the last browser to be closed on the main thread. We will fix this in our code. As a workaround, you can continue executing your code after closing the browser (within the same executor).

@mauropuravida Good afternoon! Unfortunately, the logic I want to implement doesn't fit into the described implementation option. I also noticed that if I use the standalone browser, then when I call the close method, the browser itself within the window closes, but the window does not. When I manually close the window, the program terminates

Thanks for the information. I moved the browser into a separate executable jar, which allowed me to implement what I wanted. However, it would be more convenient to work within the framework of a single project
