Here is the comment about this message from
{{StaticCompilationVisitor#checkForConstructorWithCSButClassWithout}}:
{code}
/**
* If we are in a constructor, that is static compiled, but in a class, that
* is not, it may happen that init code from object initializers, fields
* or properties is added into the constructor code. The backend assumes
* a purely static constructor, so it may fail if it encounters dynamic
* code here. Thus we make this kind of code fail
*/

And a simpler example to trigger the error:
{code}
class TestBroken {
private myField
@groovy.transform.CompileStatic
TestBroken() {}
}
{code}
