Description

I have a POJO that I use from Groovy code. After adding a setter overload, I now get IncompatibleClassChange at runtime because the static compiler generates ScriptBytecodeAdapter.setGroovyObjectProperty instead of a plain setter call.

public class Entity {
  public void setId(String id) {}
  public void setId(UUID id) {}
}

class EntityTest extends Specification {
  @CompileStatic
  Entity createEntity(String id) {
    new Entity(id: id) // uses ScriptBytecodeAdapter.setGroovyObjectProperty
  }
}

The error is not encountered when calling setId(id) or using entity.id = id, without static compilation, or when the setter is not overloaded.
