The "Field Can Be Final" transform ignores the comma operator.
This makes all fields on the same line final and causes compilation errors.

Reason for P2: Inspect and Transform should not add compilation errors.

before: 
public class Example {
    // Field a can be final
    private int a, b;
    public Example(int a, int b) {
        this.a = a;
    }
    public int getA() {
        return a;
    }
    public int getB() {
        return b;
    }
    public void setB(int b) {
        this.b = b;
    }
}

after:
public class Example {
    private final int a, b;
    public Example(int a, int b) {
        this.a = a;
        // ERROR: variable b might not have been initialized
    }
    public int getA() {
        return a;
    }
    public int getB() {
        return b;
    }
    public void setB(int b) {
        // ERROR: cannot assign a value to final variable b
        this.b = b;
    }
}

expected:
public class Example {
    private final int a;
    private int b;
    public Example(int a, int b) {
        this.a = a;
    }
    public int getA() {
        return a;
    }
    public int getB() {
        return b;
    }
    public void setB(int b) {
        this.b = b;
    }
}
