single function stops working after ADVANCED_OPTIMISATION

I tried optimize my simple code which uses jQuery. I included jQuery’s code and close it in one function with my code, to avoid any external dependencies.

Code works fine in SIMPLE_OPTIMISATION mode, and gives: ‘Uncaught TypeError: $ is not a function’ in ADVANCED_OPTIMISATION

(function(){

//jQuery without any modification included here. Omited.
/*! jQuery v1.11.1 | (c) 2005, 2014 jQuery Foundation, Inc. | jquery.org/license */

  /*this line works in SIMPLE_OPTIMISATION mode, and gives:
  'Uncaught TypeError: $ is not a function' in ADVANCED_OPTIMISATION */
  $(window);
})()

It’s likely that the jQuery code you included does not explicitly export the $ symbol, so the compiler will remove it. AFAIK the jQuery code itself is not compatible with ADVANCED_OPTIMIZATION, so a better way would be compiling just your application with the jQuery externs file (https://github.com/google/closure-compiler/blob/master/contrib/externs/jquery-1.9.js), and then bundling it with a minified jQuery code. The externs file is named jquery-1.9.js but should work under 1.11 in most cases.

Most random code are compatible with SIMPLE _OPTIMIZATIONS, making them compatible WITH ADVANCED is a non-goal for the compiler 😃
