All the time spent in FileUtil.isArchiveFile. Seems that the IO load is high which is expected during IDE start as several concurrent threads are doing IO. The problem is that the window system is doing deserialisation in EDT. Easier fix would be lazy initialisation of CPs in BaseEditorSupport rather then doing it in BaseEditorSupport.<init>. The BaseEditorSupport is a part of CookieSet.
This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue. Thanks for your cooperation, NetBeans IDE 8.2 Release Boss
