AsyncGelfHttpAppender error in OnClose() method.

When setting an invalid URL on the appender, the application crashes when trying to log with the following error:

with the following appender config:

Looking through the code, the OnClose of the appender has the _sender property set to null since the

base.ActivateOptions();

fails.

could probably fix this by just putting the _sender initialization before callind the base.ActivateOptions in the AsyncGelfHttpAppender's own ActivateOptions.

Hi!

I think the exception is correct based on that the input (URL) is invalid....

Why the library should continue executing if it's not going to do what it's expected....

Hi!

The exception is correct. I might've not been clear enough, my question would be:

On initial app load, the appender fails to be created which is what is expected. Then, it'd be expected that any logging calls just don't do anything but instead the OnClose() method of the appender is being called which causes said crash.

Why would the OnClose() method be called if it wasn't added to the root logger?

I'm sorry if I'm mistaken on something, just trying to figure this one out.

Thanks a bunch
