MSIE "Catastrophic failure" when disposing

[Daniel15]

I'm trying to use the MSIE engine and every so often I'm seeing this exception. It doesn't happen every time.

An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in MsieJavaScriptEngine.dll
Additional information: Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))

MsieJavaScriptEngine.dll!MsieJavaScriptEngine.ActiveScript.ActiveScriptJsEngineBase.Dispose(bool disposing)
MsieJavaScriptEngine.dll!MsieJavaScriptEngine.ActiveScript.ActiveScriptJsEngineBase.Finalize()

Any ideas what it could be?

I'm on Windows 8.1 and am doing this in an ASP.NET MVC website (well, a library used by an ASP.NET MVC website), using TinyIoC to register and resolve the JS engine implementation.

Let me know if you need any further information.

Hello, Daniel!

From this error message is difficult to understand its causes. But we can see that MsieJavaScriptEngine was launched in the ChakraActiveScript or Classic mode, although in Windows 8.1 is installed Internet Explorer 11 by default and, respectively, supported ChakraJsRt mode, i.e. it's not even a 'Auto' mode. It seems to me, that TinyIoC create an instance of the JavaScriptEngineSwitcher.Msie.MsieJsEngine class with wrong configuration settings.

I recommend you to create instances of JavaScript engines by using the native tools:

using (IJsEngine jsEngine = JsEngineSwitcher.Current.CreateJsEngineInstance("MsieJsEngine"))
{
    …
}

or

using (IJsEngine jsEngine = JsEngineSwitcher.Current.CreateDefaultJsEngineInstance())
{
    …
}

I'm intentionally using ChakraActiveScript because the JsRt mode seems to
have a stack overflow with the script I'm using (which unfortunately does
intentionally get pretty deep).

I'll try to dig further into this error when I get a chance, and figure out
what's going on.

Strange... In the ChakraJsRt mode hard to get the stack overflow error.

It is possible that problems in the script. Try to use a JavaScriptEngineSwitcher.V8.

What version of Internet Explorer 11 you have installed? I have installed version 11.0.9600.16476.

I found out that TinyIoC is not properly disposing resources at the end of web requests like it's supposed to (grumpydev/TinyIoC#53), so that may be part of the problem. The crash is occurring in MsieJavaScriptEngine rather than JavaScriptEngineSwitcher so perhaps I'll raise the issue in that repository instead. I'll let you know what I find out :)

[Daniel15]

Yeah it looks like this was caused by TinyIoC not disposing correctly. Fixed it now so I'll close this.

[Daniel15]

To follow up on this, the actual cause was that the engine was being disposed via a destructor, from a different thread than the one it was created on. So this was basically a duplicate of Taritsyn/MsieJavaScriptEngine#3. I have not seen it at all since fixing the code and ensuring it correctly disposes the engine :)

This bug fixed in the JavaScriptEngineSwitcher.Msie v1.1.4.
