Parsing non-JSON JavaScript object with Jackson

Question

How can Jackson be made to parse the following JavaScript object?

{
  // this is a comment
  x: '1',
  y: {
    z: '2'
  }
}

Note that the example object above is not actual JSON—it is a JavaScript object which (1) doesn't have quotes around attribute names, (2) uses single, not double, quotes around values, and (3) contains a comment.

Use case: I need to parse a JavaScript object that is embedded in HTML. I can get the JavaScript object itself, but I now need to parse it.

You can try with some parser options :

private static final ObjectMapper om = new ObjectMapper();
om.configure(JsonGenerator.Feature.ALLOW_SINGLE_QUOTES, true);
om.configure(JsonParser.Feature.ALLOW_UNQUOTED_FIELD_NAMES, true);
om.configure(JsonParser.Feature.ALLOW_COMMENTS, true);
