V6091. Suspicious getter/setter implementation. The 'A' field should probably be returned/assigned instead.

The analyzer has detected a getter/setter that accesses a field different from the one mentioned in the name.

Such errors usually result from inattention or inaccurate use of autocomplete or copy-paste.

Consider the following example:

public class Vector2i
{
  private int x;
  private int y;

  public void setX(int x)
  {
    this.x = x;
  }
  public int getX()
  {
    return x;
  }

  public void setY(int y)
  {
    this.y = y;
  }
  public int getY()
  {
    return x;              // <=
  }
}

Fixed code:

public class Vector2i
{
  private int x;
  private int y;

  public void setX(int x)
  {
    this.x = x;
  }
  public int getX()
  {
    return x;
  }

  public void setY(int y)
  {
    this.y = y;
  }
  public int getY()
  {
    return y;
  }
}

To implement methods like that, it is better to use the means provided by the IDE or code generation provided by the Lombok library.
