7.2Mule error types

You'll encounter names like:

HTTP:NOT_FOUND

HTTP:TIMEOUT

DB:CONNECTIVITY

SALESFORCE:CONNECTIVITY

SALESFORCE:INVALID_INPUT

MULE:RETRY_EXHAUSTED

Conceptually:

namespace:error-type

For example:

SALESFORCE:CONNECTIVITY

means:

connector = Salesforce
category  = connectivity

Connectors define their own error hierarchies; Mule documentation notes that connector hierarchies include common types such as CONNECTIVITY and RETRY_EXHAUSTED.
