I'm using NetBeans 7.4 RC1 with JDK8 build 108. After deactivating most of installed plugins (one of them was: "CSS Source Model"), NetBeans ask to disable also IDE Platform, but didn't suggest what plugins are required for IDE Platform, so I give it a try (I was thinking: OK, I'll disable it now, but after restarting I'll enable it with all dependencies). I was able to run NetBeans, but when I was trying to activate IDE Platfrom I've got error (IOException with some .jar file), but I was unable to copy text of the exception. I was able to activate "CSS Source Model", but even after restarting, I was unable to activate IDE Platform. It could be nice to inform user that some plugin is required and cannot be deactivated (what is strange) or fix issue with enabling IDE Platform plugin.
I guess this can be done with "essential" flag in manifest. Right, Jirko?
(In reply to Jaroslav Tulach from comment #1) > I guess this can be done with "essential" flag in manifest. Right, Jirko? I agree, an user wouldn't be able to deactivate 'core' parts of IDE w/o any possibility to activate it again. I'm going to mark it as essential.
