Eclipse automatically imports superclass for a subclass statement

I have a Parent class(from GMF to be specific) with static initializer method initDefaults

public Class Parent{

  public static initDefaults(){
   ...
  }
}

I have a custom child class that extends the Parent class

public Class CustomSubclass extends Parent{
  
  public CustomSubclass(){
   super();
   ..
  }

}

In my calling class I am calling initDefaults method with the CustomSubclass name i.e., CustomSubclass.initDefaults() but eclipse automatically corrects this and types Parent.initDefaults().

public Class ExampleClass{

  public void initializer(){
    // CustomSubclass.initDefaults(); this is what I typed
    Parent.initDefaults(); // this is what eclipse corrected
    ...
  }
}

Both ExampleClass and CustomSubclass reside under same package while Parent is from GMF as dependency.

Why is this happening? I have other plugin project with the same setup and there this is not the case and the CustomSubclass name is retained as it is. But I did not implement the other plugin project.

Whenever I am typing the subclass name with superclass method, the superclass is automatically imported and eclipse corrects the subclass name with the superclass name.

Solution

  • Eclipse provides for this code smell (the compilation would not fail, but it's harder to read, a bit slower and there is no real benefit since static methods cannot be overridden):

    These defaults can be overridden by the following project specific settings (tick the Enable project specific setting checkbox):
