How can I add a custom exception (extending TemporalException) to workflow exception types `(WorkflowImplementationOptions.failWorkflowExceptionTypes)` in **Springboot**? So it will not be retried.

Throwing an exception like this `throw ApplicationFailure.newNonRetryableFailure` from the workflow fails the workflow. However, I am hoping to fail the workflow using a custom exception.

It’s not possible currently to specify WorkflowImplementationOptions, see feature request [here](https://github.com/temporalio/sdk-java/issues/1647).

Until it’s added would use ApplicationFailure (you don’t have to throw nonRetryable kind, workflows do not have default retry policy like activities).  
Re-throwing ActivityFailure/ChildWorkflowFailure would fail workflow execution as well.

What is the use case where you want to explicitly fail the execution?
