Description Rachel_Greenham 2014-07-21 10:19:48 UTC

Build: NetBeans IDE 8.0 (Build 201403101706)
VM: Java HotSpot(TM) 64-Bit Server VM, 25.11-b03, Java(TM) SE Runtime Environment, 1.8.0_11-b12
OS: Mac OS X

User Comments:
Rachel_Greenham: I happened to leave it running overnight. The following morning, it was mostly unresponsive (attempts to interact mostly just resulted in a short-lived beachball). I tried quitting (normally); after a while all the window/menu disappeared and there was no apparent sign of it except in the Force Quit dialogue. (I forgot to check activity monitor)

Eventually hit force-quit.

org.netbeans.core.startup.preferences.NbPreferences$UserPreferences#403 1,019,113,627
one pref node occupies over 1G :-). Fanis, what good is NbPreferences.cachedKeyValues? It contains over 1mil items. If you really need a history, can it be a limited one?
Maven indexer called Prefs.put() many times over user's session and NbPreferences just collected all of those values.

This should be fixed by http://hg.netbeans.org/main-silver/rev/6ad45f1e33cb. Please try a latest build and reopen if it still happens for you. Thank you
