AbstractJsonPartialMatcher: Regex Value is Uppercased when IgnoreCase is set to true

[epDugas]

Describe the bug

AbstractJsonPartialMatcher When IgnoreCase is true, and Regex is true, the value used as a regex is upper-cased. This changes a given regex and causes a non-match. Example: "^\d+$" is changed to "^\D+$"

Expected behavior:

Expect the given regex to be used.

Test to reproduce

• Create a request mapping, with Regex = true and IgnoreCase = true
• Define json object with regex: { "x" : "^\d+$" }

Test to Demonstrate:

[Fact]
public void JsonPartialWildcardMatcher_IsMatch_WithIgnoreCaseTrueAndRegexTrue_JObject()
{
    // Assign 
    var matcher = new JsonPartialWildcardMatcher(new { id = 1, Number = "^\\d+$" }, true, true);

    // Act 
    var jObject = new JObject
    {
        { "Id", new JValue(1) },
        { "Number", new JValue(1) }
    };
    double match = matcher.IsMatch(jObject).Score;

    // Assert 
    Assert.Equal(1.0, match);
}
