Aaron Dossett updated HADOOP-12284:
-----------------------------------
Description:
If doAs() catches a PrivilegedActionException it extracts the underlying cause
through getCause and then re-throws an exception based on the class of the
Cause. If getCause returns null, this is how it gets re-thrown:
else {
throw new UndeclaredThrowableException(cause);
}
If cause == null that seems misleading. I have seen actual instances where
cause is null, so this isn't just a theoretical concern.
