which itself is a RuntimeException.
Exceptions which can be thrown from specific CEM calls are documented with the call. Other exceptions are more generic and can occur anytime there is a problem with the underlying WebSphere WorkArea facility on which CEM depends.
If the WebSphere WorkArea facility is not available in the application's environment, exceptions are not raised, but some calls return nulls. It is up to the application writer to check whether a null value has been returned by a CEM call.
CEM shares the WebSphere WorkArea facility with other parts of the same application. This means that the application writer should take care not to corrupt data that belongs to CEM; keys owned by CEM are prefixed with "ECSID:". Several of the exceptions listed here can result from such corruption
