Class ExceptionThrower

public final class ExceptionThrower
extends Object

Because we need the functionality of throwing any exception not only in PatternTesting Exception but also here this functionality was shifted to PatternTesting Runtime.
This class is not intended for public use. If you do so use it on your own risk!
