Review Comment:
**Security Issue**: Using Collection's size() to check for emptiness can be
less efficient than using isEmpty(). <br> **Fix**: Use isEmpty() to check for
collection's emptiness for better performance. <br> **Code Suggestion**:
```

Review Comment:
**Performance Issue**: Null check for 'registryConfig' before accessing its
'getScopeModel()' method to prevent potential NullPointerException. <br>
**Fix**: Add null check for 'registryConfig' before dereferencing it to ensure
safety and avoid NullPointerException. <br> **Code Suggestion**:
```

Review Comment:
**Scalability Issue**: Usage of raw type ArrayList for URLs collection
compromises type safety. In a highly scalable system, ensuring type safety is
crucial for maintaining data integrity and system stability under load. <br>
**Fix**: Change the declaration from raw type to a parameterized type to ensure
type safety. For example, use 'List<URL>' instead of just 'List'. <br> **Code
Suggestion**:
```
- protected final transient List<URL> urls = new ArrayList<URL>();
+ protected final transient List<URL> urls = new ArrayList<>();
