AuthAPI's resetPassword method doesn't throw exception when the user doesn't exist with given emailAddress

I was just running a use case to sent reset password link using the Java SDK. I have used the resetPassword method here

On using an emailAddress with which no user has been registered. I could see a failed change password log on the dashboard. But I didn’ t get an exception at the method invocation end.

Is this the expected behavior or a bug?

We had discussion regarding this here
This is perhaps a desired feature of Auth0.
