V8Object debugScope = runtime.getObject(DEBUG_OBJECT_NAME); debugScope is UNDEFINED , and the next steps get exception.

Hi, V8DebugServer is not compatible with J2V8 6.2. You have to use V8Inspector instead.

To establish communication with Chrome DevTools, you have to create a WebSocket based HTTP server then forward messages from Chrome DevTools to V8Inspector.dispatchProcotolMessage.

FYI - you can use https://github.com/AlexTrotsenko/j2v8-debugger for this. I wrote a blog post about updating it to use the Inspector protocol. https://engineering.salesforce.com/debugging-embedded-javascript-in-an-android-app-using-chrome-devtools-8553864ee09c
