Pulling up static members does not update references qualified with the class name correctly, which can break the code. Example:

public class X {}
public class Y extends X {
	
	private static int x = 0;

	public static int getX() {
		return x;
	}

	public static void setX(int x) {
		Y.x = x;
	}
}

Pulling up all (static) members produces:

public class X {

	private static int x = 0;


	public static int getX() {
		return x;
	}

	public static void setX(int x) {
		Y.x = x;  // does not compile, should be X.x = x;
	}
}
class Y extends X {}

This does not compile. To make matters worse the uncompilable code is green in the editor, see IDEA-16937. This issue may also be related to IDEABKL-4822
