Details
An Error is a subclass of Throwable that indicates serious problems that a reasonable application should not try to catch. Most such errors are abnormal conditions. The ThreadDeath error, though a "normal" condition, is also a subclass of Error because most applications should not try to catch it.

A method is not required to declare in its throws clause any subclasses of Error that might be thrown during the execution of the method but not caught, since these errors are abnormal conditions that should never occur.

public Error(Throwable cause) Details
Constructs a new error with the specified cause and a detail message of (cause==null ? null : cause.toString()) (which typically contains the class and detail message of cause). This constructor is useful for errors that are little more than wrappers for other throwables.
causethe cause (which is saved for later retrieval by the #getCause() method). (A null value is permitted, and indicates that the cause is nonexistent or unknown.)
