Simple test fails to load initial web page

magreenblatt commented 3 years ago

Original report by Francisco Vega (Bitbucket: francisco_vega).

Simple test is not loading google page when executed (panel keeps blank). Detailed test works.

After updating to java-cef release v1.0.10-92.0.25+gd15cfa8+chromium-92.0.4515.131 the Simple test is not working. In the previous release it was working.

Tested in win32 with Java 8 and win64 with Java 11.

After some investigations comparing Simple and Detailed tests, I have discovered a workaround.

If you insert in MainFrame.java the second and third line after the first one, it works again:

    client_ = cefApp_.createClient();
    CefMessageRouter msgRouter = CefMessageRouter.create();
    client_.addMessageRouter(msgRouter);

So, it seems that adding a message router has become “mandatory” in some way. At least in Windows.

I will try to go deeper into the problem.

I stumbled into this same issue when I was building my own JCEF application (Peeking the examples for concepts that I need I skipped message router as I don’t need any of the message router features in the detailed example) and when testing my app the render thread always died after comparin my app to the detailed example and finally some googling I stumbled to this issue and adding this workaround made everything work fine in my own application.

I currently use binary build that has following version information:
JCEF Version = 92.0.25.283
CEF Version = 92.0.25
Chromium Version = 92.0.4515.131
