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.

cause is not automatically incorporated in
this error's detail message.
Params:

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.
Params:
cause – the cause (which is saved for later retrieval by the Throwable.getCause() method). (A null value is
        permitted, and indicates that the cause is nonexistent or
