Review Comment:
**Security Issue**: The change from 'new ArrayList<URL>()' to 'new
ArrayList<>()' in the declaration of 'urls' uses diamond syntax for cleaner
code. This modification does not introduce a security issue directly. However,
the context in which this list is used should be reviewed to ensure that URL
objects added to this list are validated to prevent any potential security
vulnerabilities, such as URL redirection, SSRF, or information disclosure
vulnerabilities. <br> **Fix**: Ensure that any URL objects added to the 'urls'
list are properly validated against a whitelist of allowed URLs or sanitized to
prevent malicious inputs. <br> **Code Suggestion**:
```

+ protected final transient List<URL> urls = new ArrayList<>();

Review Comment:
**Security Issue**: Adding a null check for 'registryConfig' before
accessing its 'getScopeModel()' method improves the robustness of the code and
prevents potential NullPointerException. This is a good practice to avoid
crashes due to dereferencing null pointers. <br> **Fix**: Implement the null
check as shown in the code suggestion to prevent NullPointerException. <br>
**Code Suggestion**:
```
- if (registryConfig.getScopeModel() != applicationModel) {
+ if (registryConfig != null &&
registryConfig.getScopeModel() != applicationModel) {
```
