- return type: `boolean`

Description: This method is called when an optimizer hard\-failed and generated an exception. 

 **Implementation note:** the default implementation logs an error to the console, reports the error, and will let the master optimizer resume execution if allowed.
parameter: target: the target that being optimized
parameter: opt: the failing optimizer
