Hi bgitaadji,

ad 1,2 : The transaction is rolled back to the latest wait state. http://activiti.org/userguide/index.html#bpmnConcurrencyAndTransactions
ad 3: The response is returned to the event initiator. (e.g I complete user task through REST API. Next service task throws an exception. The exception is propagated as a response to this REST API call.) Another type of error handling is handling of asynchronous jobs http://activiti.org/userguide/index.html#failRetry.
ad 4: logging configuration is managed by the possibilities of the underlying logging framework.

Martin

For starters, your logs will show it.
If it's an async task, the exception will be stored in the job database and you can query for it.
