Line range hint
82-117: Consider refactoring to make the enum immutable.The current implementation uses mutable state through the
varsmap and setter methods, which is an anti-pattern for enums. Enums should be immutable to ensure thread-safety and prevent unexpected state changes.Consider refactoring to a builder pattern or message template approach:
public enum IbanValidationResult { - private final Map<String, String> vars = new HashMap<>(); + private final String message; + private final Map<String, String> vars; IbanValidationResult(final String message) { this.message = message; + this.vars = new HashMap<>(); } + public static IbanValidationResult withVars(IbanValidationResult result, Map<String, String> vars) { + IbanValidationResult newResult = result; + newResult.vars.putAll(vars); + return newResult; + } - void setFound(final String found) { - this.vars.put("found", found); - } // Remove other setter methods similarly
Line range hint
63-67: Potential security vulnerability in message templating.The
message()method uses direct string replacement which could be vulnerable to injection if the input values aren't properly sanitized. WhileescapeEcmaScriptis used, it may not cover all cases.Consider using a proper templating library or implementing stricter validation:
public String message() { String msg = this.message; for (Entry<String, String> e : vars.entrySet()) { - msg = msg.replace("${" + e.getKey() + "}", escapeEcmaScript(e.getValue())); + // Validate key against whitelist + if (!ALLOWED_KEYS.contains(e.getKey())) { + throw new IllegalArgumentException("Invalid template key: " + e.getKey()); + } + // Apply stricter escaping and validation + String value = strictEscape(e.getValue()); + msg = msg.replace("${" + e.getKey() + "}", value); } return msg; }src/test/java/com/prowidesoftware/swift/constraints/IbanValidatorTest.java (1)

171-180: Consider implementing the disabled test case.There's a TODO comment indicating that a test case for invalid characters validation is needed. Since this PR addresses IBAN validation problems, it might be worth implementing this test case now.
Would you like me to help implement this test case or create a GitHub issue to track this task? I can analyze the validation logic to suggest appropriate test inputs that would trigger the

1-1643: Consider adding schema validationGiven the complexity and size of this configuration file, consider adding JSON schema validation to ensure:
- Consistent structure across all country entries
- Valid character types ('n', 'a', 'c')
- Required fields are present
- Length values are positive integers
Example schema structure:
{ "$schema": "http://json-schema.org/draft-07/schema#", "type": "array", "items": { "type": "object", "required": ["country_code", "validation_rules"], "properties": { "country_code": { "type": "string", "pattern": "^[A-Z]{2}$" }, "validation_rules": { "type": "array", "items": { "type": "object", "required": ["entry_type", "length", "character_type"], "properties": { "entry_type": { "type": "string", "enum": ["bank_code", "branch_code", "account_number", "national_check_digit", "account_type", "currency"] }, "length": { "type": "integer", "minimum": 1 }, "character_type": { "type": "string", "enum": ["n", "a", "c"] } } } } } } }

45-45: LGTM! Typo fix improves code clarity.
The rename from IVALID_CHECK_DIGITS to INVALID_CHECK_DIGITS is a good correction that improves code readability and maintains consistency.
src/test/java/com/prowidesoftware/swift/constraints/IbanValidatorTest.java (1)
184-184: LGTM! Verify enum constant usage.
The fix for the typo in the enum constant (IVALID → INVALID) is correct.
Let's verify that this enum constant is consistently used across the codebase:
✅ Verification successful
Enum constant usage is consistent across the codebase
The search results confirm that:
- No instances of the old
IVALID_CHECK_DIGITSremain in the codebase - The new
INVALID_CHECK_DIGITSconstant is consistently used in both the enum definition and all its usages - The related constant
INVALID_CHECK_DIGITS_FORMATis also properly used
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:

265-266: LGTM! Valid Israeli IBAN test case added.
The test case follows the correct format and pattern for Israeli IBANs.
362-362: LGTM! Improved assertion parameter order.
The change follows JUnit best practices by putting the expected value first in the assertion, which provides clearer error messages on test failures.

1331-1333:
Unique validation rule for currency field
The SC (Seychelles) country code includes a unique 'currency' entry type that isn't present in other country validations. This inconsistency might indicate:
- A special case that needs documentation
- A potential error in the validation rules
#!/bin/bash
# Description: Check for currency field usage
echo "Searching for currency validation usage..."
rg -l 'currency.*validation'
echo "Checking for currency-related tests..."
rg -l 'test.*currency.*SC'Please verify if this is intentional and add documentation explaining the special case for Seychelles.
16-19: 🛠️ Refactor suggestion
Inconsistent character type usage for account numbers
Some countries use different character types ('n' vs 'c') for account numbers without clear justification:
- AD: uses 'c' (alphanumeric)
- BY: uses 'c' (alphanumeric)
- LV: uses 'c' (alphanumeric)
This inconsistency might lead to validation issues.
#!/bin/bash
# Description: Analyze character type consistency across account numbers
echo "Analyzing account number character types..."
rg -A 2 '"entry_type":\s*"account_number"' | rg '"character_type":\s*"[^"]+"'Consider:
- Documenting the rationale for different character types
- Standardizing character types where possible
- Adding comments for cases that require specific character types
Also applies to: 231-234, 907-909
3-3:
Verify the impact of country code changes
Multiple country codes have been reorganized (e.g., AL→AD, AD→AL, BH→BA). These changes could potentially break existing implementations that rely on specific country codes.
Consider:
- Adding a migration guide for these changes
- Documenting the rationale for country code reorganization
- Ensuring all test cases are updated to reflect these changes
Also applies to: 38-38, 83-83
✅ Verification successful
Based on the comprehensive analysis of the codebase, I can now provide the final response:
Country code changes are part of a planned enhancement for IBAN validation
The changes to country codes (AD, AL, BA, BH) are part of a documented enhancement (PW-2040) that adds IBAN validation support for 88 countries. This is a deliberate improvement, not an error, as evidenced by:
- The changelog entry: "Added IBAN validation for the 88 supported countries"
- Comprehensive test coverage in IbanValidatorTest.java for country code validation
- Well-structured validation rules in the JSON file for each country
The changes are properly implemented with:
- Complete validation rules for each country
- Consistent format and structure
- Proper test coverage for validation scenarios
