Invalid registry object on workbench shutdown

[Holzmacher]

I use eclipse rcp 4.33 (https://download.eclipse.org/eclipse/updates/4.33/). When i close the program i get the following error:

org.eclipse.core.runtime.InvalidRegistryObjectException: Invalid registry object at org.eclipse.core.internal.registry.RegistryObjectManager.basicGetObject(RegistryObjectManager.java:293) at org.eclipse.core.internal.registry.RegistryObjectManager.getObject(RegistryObjectManager.java:283) at org.eclipse.core.internal.registry.ConfigurationElementHandle.getConfigurationElement(ConfigurationElementHandle.java:29) at org.eclipse.core.internal.registry.ConfigurationElementHandle.createExecutableExtension(ConfigurationElementHandle.java:65) at org.eclipse.ui.internal.commands.CommandStateProxy.loadState(CommandStateProxy.java:177) at org.eclipse.ui.internal.commands.CommandStateProxy.loadState(CommandStateProxy.java:161) at org.eclipse.ui.internal.commands.CommandStateProxy.shouldPersist(CommandStateProxy.java:255) at org.eclipse.ui.internal.commands.CommandService.dispose(CommandService.java:142) at org.eclipse.ui.internal.services.ServiceLocator$3.run(ServiceLocator.java:180) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:47) at org.eclipse.ui.internal.services.ServiceLocator.disposeServices(ServiceLocator.java:177) at org.eclipse.ui.internal.services.ServiceLocator.dispose(ServiceLocator.java:150) at org.eclipse.ui.internal.Workbench.shutdown(Workbench.java:3040) at org.eclipse.ui.internal.Workbench.busyClose(Workbench.java:1141) at org.eclipse.ui.internal.Workbench.lambda$4(Workbench.java:1414) at org.eclipse.swt.custom.BusyIndicator.showWhile(BusyIndicator.java:67) at org.eclipse.ui.internal.Workbench.close(Workbench.java:1414) at org.eclipse.ui.internal.Workbench.close(Workbench.java:1385) at org.eclipse.ui.internal.WorkbenchWindow.busyClose(WorkbenchWindow.java:1720) at org.eclipse.ui.internal.WorkbenchWindow.lambda$5(WorkbenchWindow.java:1747) at org.eclipse.swt.custom.BusyIndicator.showWhile(BusyIndicator.java:67)

It looks like the error doesn't apear with all Eclipse RCP. But I haven't figured out why this happens in my application yet.

For me it seems there is something wrong with the order of dispose of shutdown. Maybe the registry object is disposed too fast.

could you please contribute a fix?

@Holzmacher , did you ever find a solution or work around? I'm seeing a similar issue and haven't been able to address it myself.

[Holzmacher]

@andrew-tram No. Found no solution or workaround.

@Holzmacher , I have a discussion ticket for Equinox here - https://github.com/eclipse-equinox/p2/discussions/690

Though not exactly your case as you were seeing issues on 4.33, while I did not, I think some of the information in there may be relevant to finding some fix for this.
