Class InvocationTargetException

public class InvocationTargetException extends Exception

InvocationTargetException is sort of a way to "wrap" whatever exception comes up when a method or constructor is called via Reflection. As of JDK 1.4, it was retrofitted to match the exception chaining of all other exceptions, but getTargetException() still works.

Since: 1.1
