Bug 79507 [quick assist] "Inverse if statement" quick assist doesn't work
"Inverse if statement" quick assist replaces if (args.length > 5) System.out.println("OK"); else if (args.length < 3) System.out.println("KO"); with if (args.length <= 5) if (args.length < 3) System.out.println("KO"); else System.out.println("OK");
