RAD.java throws an NPE when isForceDiff is not passed as constructor arg

[sumitraina]

The constructor for the class RAD expects an optional argument for the class member isForceDiff which is a Boolean wrapper (line 46). If the argument is not passed in, the member stays null.

line 46: this.isForceDiff = Boolean.parseBoolean(parameters[3]);

This throws an NPE at line 181 where the code checks if (this.isForceDiff).
line 181: } else if (this.isForceDiff) {

To overcome this, isForceDiff has to be passed at least as False.

Fix: The code should check for null at line 181 or make isForceDiff primitive for it to default to false.
