The standard runtime BPEL faults can occur due to errors in the design of a process (for example, having two receives executing concurrently on the same partner link and operation results in a
) as well as standard runtime errors. In general, it is not good design practice to catch these faults since they mostly represent errors that should be caught during simulation or testing of the process. There are some exceptions to this. For example,
is useful for identifying a situation where an activity does not execute due to its inbound links resulting to false.
