ActivationException

public class ActivationException extends Exception
General exception used by the activation interfaces.

As of release 1.4, this exception has been retrofitted to conform to the general purpose exception-chaining mechanism. The "detail exception" that may be provided at construction time and accessed via the public {@link #detail} field is now known as the cause, and may be accessed via the {@link Throwable#getCause()} method, as well as the aforementioned "legacy field."

Invoking the method {@link Throwable#initCause(Throwable)} on an instance of ActivationException always throws {@link IllegalStateException}.
