 When this module is present, Gson can use the `Unsafe` class to create instances of classes without no-args constructor.
 However, care should be taken when relying on this. `Unsafe` is not available in all environments and its usage has some pitfalls,

-The problem here is the trailing comma (`,`) after `"French"`, trailing commas are not allowed by the JSON specification. The location information "line 5 column 4" points to the `]` in the JSON data (with some slight inaccuracies) because Gson expected another value after `,` instead of the closing `]`. The JSONPath `$.languages[2]` in the exception message also points there: `$.` refers to the root object, `languages` refers to its member of that name and `[2]` refers to the (missing) third value in the JSON array value of that member (numbering starts at 0, so it is `[2]` instead of `[3]`).

 The proper solution here is to fix the malformed JSON data.
 
 To spot syntax errors in the JSON data easily you can open it in an editor with support for JSON, for example Visual Studio Code. It will highlight within the JSON data the error location and show why the JSON data is considered invalid.
