Attributes

Remarks

Produces a method handle which will throw exceptions of the given exType. The method handle will accept a single argument of exType, and immediately throw it as an exception. The method type will nominally specify a return of returnType. The return type may be anything convenient: It doesn't matter to the method handle's behavior, since it will never return normally.
