ACL2
Explanation
The CICS Foundation Classes invoked the default handleEvent method (defined in class IccResource) in order to handle a CICS condition because the application programmer did not implement his own handleEvent method.
System action
CICS abnormally terminates the transaction.
User response
Implement your own handleEvent method or customize your resource objects so they do not call the handleEvent method for any of the possible CICS conditions.
