As it is announced in jQuery 1.11.0/2.1.0 Beta 2 Released the source map comment will be removed so the issue will not appear in newer versions of jQuery.

Here is the official announcement:

One of the changes we’ve made in this beta is to remove the sourcemap comment. Sourcemaps have proven to be a very problematic and puzzling thing to developers, generating scores of confused questions on forums like StackOverflow and causing users to think jQuery itself was broken.

Anyway, if you need to use a source map, it still be available:

We’ll still be generating and distributing sourcemaps, but you will need to add the appropriate sourcemap comment at the end of the minified file if the browser does not support manually associating map files (currently, none do). If you generate your own jQuery file using the custom build process, the sourcemap comment will be present in the minified file and the map is generated; you can either leave it in and use sourcemaps or edit it out and ignore the map file entirely.

Here you can find more details about the changes.

Here you can find confirmation that with the jQuery 1.11.0/2.1.0 Released the source-map comment in the minified file is removed.
