  "message": "Replace makeCastMapFromArray with goog.object.createSet\n\nJCHSU.makeCastMapFromArray increases startup latency by 150ms\nin Closure/GWT hybrid apps like Google Inbox by doing more work\nduring initial load to construct cast maps.\n\nThis patch uses the closure library goog.object.createSet() function\nwhich accomplishes the same task, but has a builtin closure compiler\noptimization which turns var-arg arguments into a static object literal.\n\nChange-Id: Ia091e280c305c7f7964fd25bb0d2197aa0245ea0\n",
