This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
(First noticed this two weeks ago and thought it could be due to patches on my system - but it happens both on my PC and Mac when building against pristine checkouts). Build NB from source. Start it. Open some project. Shut down normally. Restart it. A NoClassDefFoundError is thrown during startup and startup does not continue. Deleting $USERDIR/var/cache/* works to fix it for one restart. It appears that org.netbeans.editor.options.BasePrintOptions has either disappeared or its visibility has changed such that it's serialized but can't be instantiated on restart.
Created attachment 20427 [details] Stack trace from startup
Adding Jarda to cc; I'm wondering if we should include a restart on a used userdir as part of commit validation - the fact that NetBeans has been unusable on restart for a few weeks and I didn't find any existing P1 bug about it is a little scary - it can't just be me if it's happening on both my pc and my mac. I can't believe I'm the only person who noticed - my job doesn't even requre me to build NB daily anymore.
Duplicate of some bug I am not able to find now. You need to do ant clean; cvs up; ant otherwise there maybe some garbage on your disk from previous compilation. The fix in your case is likely to remove properties module and check out clean version.
duplicate of issue #54252
