JCEF Crashes on navigation from about:blank to chrome:versio

Postby Phylanx » Mon Dec 07, 2020 9:39 am

Hi @all!

We're currently upgrading from jcef 3325 to version 4147 and have a crash that we can't figure out how to fix.
If our own demo application starts with about:blank and we navigate to e.g. chrome:version the application crashes.
If we start with www.google.com and go to chrome:version it works.
But after google.com a navigation from about:blank to chrome:version always fails.

The problem is not reproducable with detailed MainFrame but I can't get to the problem behind it.

The crash stack is the following (as it is written to the DOS console log):
Code: Select all
15:35:57,838 DEBUG [AWT-EventQueue-0] ui.controls.UIWebBrowserCEF.CEFNativeDemo () : loadURL called! url: 'chrome:version'

This is the crashing check (render_frame_host_manager.cc(875)):
Code: Select all
CHECK_EQ(render_frame_host_->web_ui_type(),
                 WebUIControllerFactoryRegistry::GetInstance()->GetWebUIType(
                     browser_context, request->common_params().url));


We had a similar problem when we called loadURL with a dataURL not on the EventQueue, but this call runs on the EventQueue, as it is triggered by a button click.

What are we missing here or what are we doing wrong, maybe somebody can give us a hint?

Our environment is OS Windows 64 bit, OpenJDK 8u222 32bit, JCEF 4147 with 32bit binaries.
