Review Comment:
**Code Structure Issue**: Simplified the condition to check if
methodConfig.getArguments() is not empty using the isEmpty() method. <br>
**Fix**: Use !methodConfig.getArguments().isEmpty() for clarity and simplicity.
<br> **Code Suggestion**:
```
- if (methodConfig.getArguments() != null &&
methodConfig.getArguments().size() > 0) {
+ if (methodConfig.getArguments() != null &&
!methodConfig.getArguments().isEmpty()) {

Review Comment:
**Scalability Issue**: Using raw types for the ArrayList instantiation is
not type-safe and may lead to ClassCastException at runtime when incorrect
types are inserted into the list. This can potentially degrade the scalability
of the system by introducing runtime errors that are hard to debug and fix.
<br> **Fix**: Use generics for the ArrayList instantiation to ensure type
safety. This will help the system scale better by preventing ClassCastException
at runtime and making the code easier to maintain. <br> **Code Suggestion**:
```
- protected final transient List<URL> urls = new ArrayList<URL>();
+ protected final transient List<URL> urls = new ArrayList<>();
Use generics for the ArrayList instantiation to ensure type safety. This
will help the system scale better by preventing ClassCastException at runtime
and making the code easier to maintain.
