If the async task fails 3 times (the number of retries are configurable by the way), the job is kept in the database with 'retries = 0'. This won't be retries anymore, unless triggered manually by the API (or explorer). If you have async stuff in your process, you should have a mechanism that inspects the failed jobs (see JobQuery, this offers functionality to find those jobs and look at the exception that occurs) on a regular basis.

Anyway, the process won't move on and will be "waiting".

That answers my question. Just a question on this - say in our example, the mail task may be an activity to be performed, but its failure not too critical. This would imply that the process can still move to the next state. In this case is the only option currently to extend MailActivitiyBehavior? Would an option on the mail task be helpful to log the exception and continue on?

You can use a regular JavaDelegate for this and try-catch-ignore the exception in the execute() method. Activiti will consider the delegate as being executed without errors and continues it's flow.
