I have about 7 errors like this in my error log upon *every* start: ---- eclipse.buildId=4.7.0.I20170308-2000 java.version=1.8.0_102 org.eclipse.e4.ui.workbench Error Tue Mar 14 09:29:59 CET 2017 Unable to retrieve the bundle from the URI: bundleclass://org.eclipse.e4.tools.preference.spy/org.eclipse.e4.tools.preference.spy.handler.RemoveAllHandler ---- I suspect that this might be related to the application model referencing old stuff I removed/deinstalled. There are a few issues with this: - What is the error? I have to suspect what's broken. It's not clear from the message. - Why is it an error? Assuming I uninstalled/removed something - the workbench should be confused about this. It might warrant a warning that something could not be found and this warning should be logged at most once. After that it should be ignored or the model cleaned up. Please remove the error and replace it with a warning that's only logged once. If my suspicion is true, is there a bug already for cleaning up the model after deinstalling/removing things?
It's a deliberate choice that we don't remove stuff like Perspectives, ... if you uninstall a plugin - dateing even back to the 3.x days! The error you present although looks like a MHandler who indeed could be cleaned up, the problem is that I think spies are contributed to the IDE through pure e4 technology so the only possible solution would be that the spy removes it's contribution on shutdown. We once also thought about a way for contributions to be marked as volatile so that we don't persist those but we never implemented this
Thanks for helping identifying the error. Are there bugs/feature requests open for those? I'd propose to keep this one focused on error handling - which is confusing for users.
I also get 7 when I start a nested EClipse, but none of them look optional like "spy" !ENTRY org.eclipse.e4.ui.workbench 4 0 2017-09-08 10:19:08.354 !MESSAGE Unable to retrieve the bundle from the URI: bundleclass://org.eclipse.e4.tools.emf.ui/org.eclipse.e4.tools.emf.ui.internal.handlers.MarkDuplicateElementIdsHandler !ENTRY org.eclipse.e4.ui.workbench 4 0 2017-09-08 10:19:08.356 !MESSAGE Unable to retrieve the bundle from the URI: bundleclass://org.eclipse.e4.tools.emf.ui/org.eclipse.e4.tools.emf.ui.internal.handlers.MarkDuplicateLabelsHandler !ENTRY org.eclipse.e4.ui.workbench 4 0 2017-09-08 10:19:08.356 !MESSAGE Unable to retrieve the bundle from the URI: bundleclass://org.eclipse.e4.tools.emf.ui/org.eclipse.e4.tools.emf.ui.internal.handlers.MarkDuplicateAttributesHandler !ENTRY org.eclipse.e4.ui.workbench 4 0 2017-09-08 10:19:08.356 !MESSAGE Unable to retrieve the bundle from the URI: bundleclass://org.eclipse.e4.tools.emf.ui/org.eclipse.e4.tools.emf.ui.internal.handlers.RepairDuplicateItemsHandler !ENTRY org.eclipse.e4.ui.workbench 4 0 2017-09-08 10:19:08.356 !MESSAGE Unable to retrieve the bundle from the URI: bundleclass://org.eclipse.e4.tools.emf.ui/org.eclipse.e4.tools.emf.ui.internal.handlers.UnmarkItemsHandler !ENTRY org.eclipse.e4.ui.workbench 4 0 2017-09-08 10:19:08.356 !MESSAGE Unable to retrieve the bundle from the URI: bundleclass://org.eclipse.e4.tools.emf.ui/org.eclipse.e4.tools.emf.ui.internal.handlers.AutosizeColumnsHandler !ENTRY org.eclipse.e4.ui.workbench 4 0 2017-09-08 10:19:08.356 !MESSAGE Unable to retrieve the bundle from the URI: bundleclass://org.eclipse.e4.tools.emf.ui/org.eclipse.e4.tools.emf.ui.internal.handlers.ResetToDefaultHandler
Simon, please extend your cleanup add-on to remove also invalid model-addons and handlers.
(In reply to Lars Vogel from comment #4) > Simon, please extend your cleanup add-on to remove also invalid model-addons > and handlers. As discussed please move the parsing of the model for valid data into a thread (CompletableFuture comes to mind) to avoid the startup costs for the check. Only if removals are necessary we should trigger that in the main thread, preferrable via a job.

Mass change, please reset target if you still planning to fix this for 4.11.
e4 add-ons and handlers will not be persisted anymore at shutdown. Please reopen if you still can reproduce with tomorrows I-Build and a NEW workspace. Rolf, is currently working on additional cleanups but new workspaces with the new build should not have this problem anymore.

New e4 tools installation will not persist anymore. If you are OK with loosing your latest UI changes, you could start Eclipse with the -clearPersistedState flag. If you afterwards install latest e4 tools and uninstall them you should not see these errors. Removing old broken addons and handlers is planned to be done via Bug 513614. If you need this, please comment in this bug. I started to work on this yesterday and it is not a lot of work to finish this.
Will work on this based on Simons patch and Bug 558410.
Lars can you update the Target Milestone on this one?

Gerrit change https://git.eclipse.org/r/160228 was merged to [master]. Commit: http://git.eclipse.org/c/platform/eclipse.platform.ui.git/commit/?id=9157c6fe5523db8e902b338b1ba7254fa99501e2
Invalid handlers are now removed from the application model. You should see errors only once at startup, the removal is done asynchrone after startup to avoid blocking startup. The same logic should also be done for add-ons, I moved that out of this bug to Bug 561814.
