Description of motivation.
We currently have two different behaviors for the code related to
"CodeException":
```
$codebase->config->throw_exception = true; // or false
```
If "throw_exception" is set to `true`, code execution stops.
If "throw_exception" is set to `false`, the code may continue
to execute, and an error may potentially occur.
This commit allows testing for the second case, when the value of
"throw_exception" will be "false".
