Direct Known Subclasses:

MetaDataAccessException

public abstract class NestedCheckedException
extends Exception

Handy class for wrapping checked Exceptions with a root cause. This class is abstract to force the programmer to extend the class.

The similarity between this class and the NestedRuntimeException class is unavoidable, as Java forces these two classes to have different superclasses (ah, the inflexibility of concrete inheritance!).
