change access control modifier in ***Filter class

[Lojincen]

private property in ***Filter class become public

What is the motivation?

I want overrid setter method.But property is private.like:
in super class:
private float temperature;
public void setTemperature(final float temperature) {
this.temperature = temperature;
setFloat(temperatureLocation, this.temperature < 5000 ? (float) (0.0004 * (this.temperature - 5000.0)) : (float) (0.00006 * (this.temperature - 5000.0)));
}
I can not use private property in subclass

One is temperature * 0.0004,
The other is temperature * 0.00006.
That's why yellow is so light
