Java enum classes generation is broken if java code is generated to use jackson library to serialize/deserialize json into java objects and errorOnUnknownEnum is turned on.

It affects at least 3.0.36 version.

The generated code looks like:

  @JsonCreator
  public static EnumName fromValue(String input) {
    ...
    throw new IllegalArgumentException("Unexpected value '" + text + "' for 'EnumName' enum.");
  }

the issue is that the method parameter has name input, while exception text uses variable with name text to produce error message.
