public class ExceptionInInitializerError
extends LinkageError
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 Throwable.getCause() method, as well as the aforementioned "legacy method."

Method Detail
getException
public Throwable getException()
Returns the exception that occurred during a static initialization that caused this error to be created.

Returns:
the saved throwable object of this ExceptionInInitializerError, or null if this ExceptionInInitializerError has no saved throwable object.
getCause
public Throwable getCause()
Returns the cause of this error (the exception that occurred during a static initialization that caused this error to be created).
Overrides:
Returns:
the cause of this error or null if the cause is nonexistent or unknown.
