java.lang.AssertionError: Not alive: Terminating

Overall the plugin works great, but from time to time I'm receiving the following error.

Unhandled exception in [StandaloneCoroutine{Cancelling}@77516895, Dispatchers.Default]

Yeah this assertion is there in the first place to understand messaging issues (between CEF and the JVM). From this stack trace I cannot identify the root cause, maybe it's related to closing / opening files, or switching editors.

Maybe I can make this error less of an issue.

Thanks for reporting.

What info would you like to receive? I just got the error, and still have the logs...

@lestephane thanks
Yeah that could still be interesting. The nature of the exchange between the java handlers and JCef makes this exchange a bit unpractical around some edges, eg like closing an editor, etc.
