Created attachment 287764 [details] This is the result of the local debugging. It seems that the assumed iterator item time differs from the actual one.

I'm still seeing this behavior, too. Also, given the naming of the packages referenced in the error logs, is it possible that this belongs in another Product or Component category? Like, Product = WTP Common Tools and/or Component = wst.common? Just trying to think of ways to increase visibility to this bug, is all.

Like, Product = WTP Common Tools and/or > Component = wst.common? Just trying to think of ways to increase visibility > to this bug, is all. It's possible that is is a bug in WTP Source Editing. If you're still seeing this in 2022-12, you could create a WTP bug in this bugzilla. I'm not sure if the platform project is still triaging bugs here. Their development has moved to GitHub at https://github.com/eclipse-platform .
