public abstract class NestedCheckedException extends Exception
Handy class for wrapping checkedExceptionswith a root cause.This class is
abstractto force the programmer to extend the class.getMessagewill include nested exception information;printStackTraceand other like methods will delegate to the wrapped exception, if any.The similarity between this class and the
NestedRuntimeExceptionclass is unavoidable, as Java forces these two classes to have different superclasses (ah, the inflexibility of concrete inheritance!).- Author:

getMessagein classThrowable
getRootCause
public Throwable getRootCause()

nullif none
getMostSpecificCause
public Throwable getMostSpecificCause()

getRootCause()in that it falls back to the present exception if there is no root cause.- Returns:
- the most specific cause (never
null) - Since:
