Hot Swapping for Domains and their views doesn't work - restart required

So I've noticed that when I have a .gson file which renders a domain instance and then i add new properties to that domain during development, the rest of the application handles it pretty well, but from the gson i get exceptions when trying to access those new properties, for example

```
jobLayoutTemplate_gson: 19: [Static type checking] - No such property: ldBackgroundImage for class: JobLayoutTemplate
@ line 19, column 21.
ldBackgroundImage jobLayoutTemplate.ldBackgroundImage?.getSimpleInstance()
```

At that point, i gotta restart the app.

This is not a very urgent issue, as restart usually doesnt take too long, but I wanted to point out to you that hot-swapping new domain properties seems to work well otherwise, its usually the gsons that have trouble with it.

*Grails version:* 3.1.10
*Grails views:*: 1.2.6

Start by reproducing the problem with a .gson view such as jobLayoutTemplate_gson after adding a property to its domain instance. Check whether the static type-checking exception persists in Grails 3.1.10 with Grails views 1.2.6. Done means newly added domain properties can be accessed from the .gson view without restarting the application.
