public class ExceptionInInitializerError extends LinkageError
Signals that an unexpected exception has occurred in a static initializer. AnExceptionInInitializerErroris 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 theThrowable.getCause()method, as well as the aforementioned "legacy method."- Since:
- JDK1.1
