Actual result: NetBeans disables these modules so it is unusable in very important parts of its core.
Removing Netbeans user directory does not solve issue.
Reinstalled Netbeans 8.2 - the issue seems resolved. But if I install these plugin from Netbeans repository: + Color Codes Preview -- Editing + AutoSave modules -- Editing and then restart Netbeans, issue is here again.
A possible workaround for this issue that is only a diversion, because it doesn't fix anything in source code, is this: - Export all Netbeans 8.2 settings in a zip file, following Export method in settings dialog. - Uninstall Netbeans 8.2 via script uninstall.sh in Netbeans 8.2 installation directory. DO NOT REMOVE USER DIRECTORY. - Remove completely Netbeans 8.2 cache directory. - Rename Netbeans 8.2 user directory, in order to have another backup of your user data. - Reboot (maybe not necessary). - Install a fresh Netbeans 8.2, and strictly follow plugin information and migration from older Netbeans version. - Import all settings previously exported in a zip files, to have again your IDE configured as you want. - DO NOT CHECK FOR PLUGIN UPDATE, and be careful to install new plugins, because issue may return again. This is not a solution; but it is useful for temporarily using Netbeans again. IMHO, this issue remains open because it is not resolved by this workaround.
