Description Jiri Skrivanek 2011-08-22 08:34:11 UTC 
I noticed more time is spent in "Loading cached objects..." during IDE startup. Roughly measured on my watch whole startup of build 201108170601 takes 7 seconds, startup of build 201108210601 takes 12 seconds. Maybe some recent OSGi work? I am attaching profiler snapshots and log messages.

It seems netbinox is innocent in this case, because both builds contain it. Will try to investigate it further...

Comment 4 Petr Cyhelsky 2011-10-21 09:01:27 UTC 
This degradation was after all caused by introduction of netbinox and mylyn. As it is caused by loading of osgi bundles it seems it can't be easily get rid of. The degradation was this big only on windows on first start, on other operating systems it was only ~1s and it was subsequently more than compensated by some of jarda's startup speed-ups. Right now even first start on windows is on par with 7.0 as these netbinox + mylyn related degradations were compensated by fix of Issue #200848.

I'm closing this issue as wontfix.

on NetBeans 7.1.2, the issue persists whereby on start-up the splash screen load until "loading cached objects"... then is fatally stops and wont restart or continue beyond that point.   (running on fedora 17, had previously laoded the Android SDK + plugin modules, and Scala framework)
Comment 6 Jesse Glick 2012-05-08 23:08:06 UTC 
hatanet27 - this issue is about a _slowdown_, not a _halt_. Your problem is likely unrelated. Please file separately, and include your messages.log file; most likely one of your unsupported plugins is broken and preventing normal startup, but this cannot be diagnosed without a log.
