URL: https://github.com/apache/grails-core/issues/14276
In Grails 4.0.3 and Grails 3.3.11, if you have a domain class named `A`, e.g.
```{groovy}
package mypackage
abstract class A {
String name
// ...
// properties
// ...
}
```
And you populate it in `Bootstrap.groovy`, e.g.
```{groovy}
package mypackage
class BootStrap {
def init = { servletContext ->
A.withTransaction { status ->
A.saveAll(
new A( name: "a1" ),
new A( name: "a2" ),
new A( name: "a3" )
)
}
}
def destroy = {
}
}
```
If you use scaffolding (`create-scaffold-controller A`), everything works
correctly.
But if you delete the scaffolding controller and `generate-all` for your
class `A`, everything fails throwing a `java.lang.NullPointerException` because
the `AService aService` object is `null` in `AController.groovy`, i.e. the
service object is not properly injected in the controller.
Now, if you delete all the generated files except the domain class file
(`A.groovy`), rename the file and the class as, let's say, `A1`, and
`generate-all` again, everything works!
You can try with any one-letter named classes, e.g. `A`, `B`, `X`, etc., and
the generated code always fails for the same reason. Add another character to
the class name, regenerate, and everything works!
I suppose there must be some name clash somewhere when a class is named with
a single character.
