Description

When I call setNormal method of com.jme3.math.Plane, I notice that the method throws exceptions for null inputs:
public void setNormal(Vector3f normal) { if (normal == null) { throw new IllegalArgumentException("normal cannot be null"); } this.normal.set(normal); }

However, other methods do not check similar parameters. For example, I found that setOriginNormal does not throw exceptions when normal is set to null:

public void setOriginNormal(Vector3f origin, Vector3f normal){ this.normal.set(normal); this.constant = normal.x * origin.x + normal.y * origin.y + normal.z * origin.z; }

Please also add checks to avoid ill usages.

Research direction

Start at com.jme3.math.Plane and compare setNormal with setOriginNormal, then inspect the other methods that accept Vector3f parameters. Identify which null inputs need consistent validation and confirm that the affected methods reject them without changing normal or constant.
