Unable to initalize script engine due to pending script exception about clearscript HOT 2 CLOSED

Hi @ebrandin,

Has anyone seen this exception or does anyone have any ideas to what could be going on?

Currently this happens if CreateScriptEngine is called after a no-op Interrupt call – that is, an Interrupt call that occurs when the V8 runtime is not executing script code:

var runtime = new V8Runtime();
var engine = runtime.CreateScriptEngine();
engine.Interrupt();
runtime.CreateScriptEngine(); // <-- EXCEPTION

Because it may be difficult or impossible for the host to ensure that Interrupt is always called during script execution, we consider this a bug, and we'll fix it in the next ClearScript release.

However, that exception can also be legitimate. For example:

1. A script invokes a host method.
2. Interrupt is called on the same V8 runtime.
3. The host method calls CreateScriptEngine before returning to script code.

That sequence results in the same exception, and ClearScript can do nothing to prevent it. Many V8 API methods fail when a script exception (or script interruption) is pending. That behavior is by design and beyond ClearScript's control.

Thanks!

Fixed in Version 7.4.5.
