4.6.0.I20150915-2000 There's a bad interaction between two features: a) Method completion proposal that swallows a typed ")" at the end of the argument list b) Auto-insertion of ")" when the user types "(", and skipping of the ")" when typed before an existing ")" Steps: - have this code snippet and replace "|" with caret: public static void main(String[] args) { System.out.print(Stream.gen|); } - press Ctrl+Space => inserts "Stream.generate(s)", "s" selected, template mode started - type ( => inserts "(", steals the ")" after the caret and enters a nested template mode. - type ) => the closing parenthesis ends the nested template mode and makes the caret jump over the ")" that closes the generate(..) method invocation. Result (| is the caret): System.out.print(Stream.generate(()|); Note the missing ")" at the end. The problem is that functionality (b) doesn't work correctly, since the inserted ")" is wrongly consumed by the outer linked mode. The assumption that the inserted ")" closes the method invocation is invalid. Not only since the introduction of lambdas. It also happens when you complete "new Intege" and then type "(1+2)/3". We have to make sure that the method invocation proposal doesn't stop the insertion of the auto-closing ")".
