Since latest update (4.21) the type hierarchy is sometimes empty. Usually I could select a class or interface and press ctrl+t or F4 and got all classes that are extending/implementing the class/interface. But since last update the type hierarchy is sometimes empty but if I search all references in workspace (or with ctrl+shift+g) I find also classes that are implementing/extending the interface/class. If I open such a class, select the interface (after the implementing keyword) and press ctrl+t the interface and the implementing class is shown. If I open the editor of the interface and press ctrl+t the hierarchy is empty again.
Would be great to have minimal steps to reproduce. Any errors in the log? Is autobuild enabled? Any additional plugins that might interfere?

Better: start with a fresh new workspace please and try to reproduce the problem. Once you have it, please attach the log file and ideally steps to reproduce. Your current workspace shows a lot of broken dependencies, missing bundles etc. Not sure if that is somehow related to the problem you observe, but if you really want to solve your issues, please just throw away this workspace and start from scratch.
I'll try this if I find the time to setup a fresh workspace. Is there something to automate the setup of a workspace? We already have a p2f-File with our plugins and some templates (formatter, templates, cleanup) but they have to be imported and configured manually. Also compiler-settings etc. have to be done manually.. Maybe someone has a hint to make the whole process easier.
Hi, I have the same issue since upgrade to 4.21. Just open any workspace which contains some Java projects, open some interface (which you know that has some implementations or extending interfaces) and choose "Quick type hierarchy" (Ctrl+T, ...). Only parent interfaces are presented. PS. The only error in workspace log file which I have (does not appear to be related to the problem): !ENTRY org.eclipse.e4.ui.workbench 4 0 2021-10-28 15:51:59.678 !MESSAGE Unable to retrieve the bundle from the URI: bundleclass://com.genuitec.eclipse.meexplorer/com.genuitec.eclipse.meexplorer.breadcrumb.e4.BreadCrumbContainer
last friday I've renewed my local installation -> deleted eclipse, deleted workspace, deleted ~/.p2, deleted ~/.eclipse it seems that the issue is now solved but I'll have an eye on it. :-)
I also had this issue in multiple workspaces. Closing and reopening all projects fixed it for me and it have not reappeared.
(In reply to Bjarke Skjernaa from comment #10) > I also had this issue in multiple workspaces. Closing and reopening all > projects fixed it for me and it have not reappeared. Clearly the problem is a real problem experienced by multiple users. It has not been fixed. It is not invalid. It is just a pain to reproduce. I just had similar problems with deficient sub-Type Hierrachy content. It remained deficient after a restart and close + clean all. (Specifically /org.eclipse.ocl.pivot/src/org/eclipse/ocl/pivot/ids/PropertyId.java showed a supertype but no subtypes.) However it did not reproduce in another workspace. Workaround: It was fixed by close then open project. Clearly there is some kind of caching issue that survives a restart but not a reopen, and presumably some kind of error puts the cache in a bad state.
I also encountered this issue after upgrading Eclipse from 4.20 to 4.21. Usually I install the new version side-by-side and create a new workspace. However, this time, I did an in-place upgrade and continued using the same workspace. I found that removing .metadata/.plugins/org.eclipse.jdt.core corrected the issue. So it seems like something was preventing the indexes from being read or updated. The indexNamesMap.txt and savedIndexNames.txt mention INDEX VERSION 1.131 - though I don't know if that the same version Eclipse 4.10 used. Maybe there was a version migration and some data got corrupted? The interesting thing is that it doesn't appear to generate any error messages in .metadata/.log when it's broken. I still have the broken folder backed-up, but unfortunately I doubt I'd be able to share - it's from a work environment. But if there are things I can try/inspect, I'll do what I can.
(In reply to Ed Willink from comment #11) > Workaround: It was fixed by close then open project. ^^^^^^^^^^ Thank you so much for this! Absolutely made my day. I had the sane issue,, which manifested itself upon migrating my workspace from 4.20 to 4.21 (and persisted after migrating to 4.22). I can confirm that closing and re-opening all projects in the workspace (in one go) appears to have fixed it permanently. This made me realize just how critical this functionality is in navigating my code; I felt totally lost when it misbehaved. I have inheritance relationships spanning multiple projects.
I confirm that closing/opening the projects brings both "Quick Type Hierarchy" and "Open Implementation" back to live. Without those features working the environment feels deficient and crippled.
