Signals that an unexpected exception has occurred in a static initializer.
An ExceptionInInitializerError
is thrown to indicate that an
exception occurred during evaluation of a static initializer or the
initializer for a static variable.
As of release 1.4, this exception has been retrofitted to conform to
the general purpose exception-chaining mechanism. The "saved throwable
object" that may be provided at construction time and accessed via
the getException()
method is now known as the cause,
and may be accessed via the getCause()
method, as well
as the aforementioned "legacy method."
