Show critical errors via MessageBox, not just recaf-launcher.log

[Yoticc]

For example, when I open the launcher.jar it doesn't open, I don't see MessageBox with error, to understand what happened, I have to open recaf-launcher.log to find the line with an error.
In that case log is:

Attempting to resolve installed Recaf version...
Recaf jar file not found: 'C:\Users\u\AppData\Roaming\Recaf\recaf.jar'

It would be nice to see a MessageBox with error:

Recaf jar file not found:
``C:\Users\u\AppData\Roaming\Recaf\recaf.jar''.

I think it won't be a problem to make MessageBox display via jfx

MessageBox display via jfx

The launcher has no dependency on JFX so it'd be in swing, but I agree this would be a nice to have feature for usability.

Wait, are you saying when you open the launcher the GUI does not show up?

The way this works is that if you run it via java you get the CLI. But if you use javaw which is how most OS's pair .jar file associations you get the GUI. This is intentional, you don't wan the CLI to pop open dialog windows.

I think it's because I had jre8 and jre11 on my PC, but not jre17. This was fixed after installing jre17 when I tried to build the recaf-ui module. I used java -jar but at the same time tried java.exe and javaw.exe from jre8, as I remember

pointing out the obvious, javaw is not existent on linux for example
