public abstract class StackableException
extends java.lang.Exception

A baseclass for exceptions, which could have parent exceptions. These parent exceptions are raised in a subclass and are now wrapped into a subclass of this Exception.

The parents are printed when this exception is printed. This class exists mainly for debugging reasons, as with them it is easier to detect the root cause of an error.
