Review Comment:
**Suggestion**: Adding a null check before accessing the 'getScopeModel()'
method is a good practice to avoid potential NullPointerExceptions. <br> **Code

Review Comment:
**Security Issue**: Null check is added before accessing the
'registryConfig.getScopeModel()'. This prevents potential NullPointerExceptions
when registryConfig is null. <br> **Fix**: Ensure that registryConfig is not
null before accessing its methods or fields to avoid NullPointerException. <br>
**Code Suggestion**:
```
- if (registryConfig.getScopeModel() != applicationModel) {

registryConfig.getScopeModel() != applicationModel) {

**Scalability Issue**: Using '!methods.isEmpty()' is more readable and
