Avoid Catching Generic CX_ROOT

WarningSecurity & Robustness#EC CATCH_ROOTRemote Enabled

Overview

Catch specific exceptions instead of generic cx_root.

ATC Finding Message: Avoid generic CATCH cx_root; catch specific exception classes instead

Rationale

Catching CX_ROOT catches programming errors, resource shortages, and runtime failures together with expected business exceptions. The handler cannot respond correctly to all of them and may hide serious defects. Catch only the specific exception types you can handle and let everything else propagate.

Non-Compliant

TRY.
  process_order( ).

Compliant

TRY.

  logger->record( lx_order ).
ENDTRY.
