bug in java code generation for Enumeration in swagger document

[MeghaPunj]

For java code generation from swagger, for enums, there is a bug in code generation.
I have tried many versions so far but no luck. To replicate the issue, please take the latest stable version or this:

<swagger.codegen.version>3.0.45</swagger.codegen.version>
I have already added under properties:
<errorOnUnknownEnum>true</errorOnUnknownEnum>

The code generated has:

"Unexpected value '" + text + "' for 'MyTest' enum."
instead of:
"Unexpected value '" + input+ "' for 'MyTest' enum."

@JsonCreator
    public static TypeEnum fromValue(String input) {
      for (TypeEnum b : TypeEnum.values()) {
        if (b.value.equals(input)) {
          return b;
        }
      }
      throw new IllegalArgumentException("Unexpected value '" + text + "' for 'MyTest' enum.");
    }

Also there is mention of this change here:
#713

May be the same is missing in the latest version 3.x.x
