Which statement is FALSE about error handling in the ESB profile?

If you do not define a fault sequence, in the case of an error in a sequence or a proxy service, an exception will be thrown and the message will be dropped.

In situationswhere a fault sequence is not specified explicitly, a default fault sequence will be used to handle errors.

Within the fault sequence, you can access error details using the ERROR_DETAIL property.

The Fault mediator can be used to customize error messages that are sent back to the client.
