This morning I updated Eclipse to the latest version. Since then, I have been unable to use the Delete key in the editor. It works fine in other applications, but inside Eclipse, Delete, Ctrl-Delete, and Shift-Delete have no effect. Attempting to remap the key causes an error: An error has occurred. See error log for more details. loader constraint violation: when resolving interface method "org.eclipse.e4.ui.bindings.EBindingService.getPerfectMatch(Lorg/eclipse/jface/bindings/TriggerSequence;)Lorg/eclipse/jface/bindings/Binding;" the class loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) of the current class, org/eclipse/ui/internal/keys/BindingService, and the class loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) for resolved class, org/eclipse/e4/ui/bindings/EBindingService, have different Class objects for the type org/eclipse/jface/bindings/TriggerSequence used in the signature I have also noticed that Ctrl-Z does not work in Eclipse any more. Naturally, this is a serious problem.
What does version and build information does Help > About show?
The same happend to me today: I have Eclipse Juno SDK Version: 4.3.0 Build id: I20121214-0730 the full error is: An error has occurred. See error log for more details. loader constraint violation: when resolving interface method "org.eclipse.e4.ui.bindings.EBindingService.getPerfectMatch(Lorg/eclipse/jface/bindings/TriggerSequence;)Lorg/eclipse/jface/bindings/Binding;" the class loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) of the current class, org/eclipse/ui/internal/keys/BindingService, and the class loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) for resolved class, org/eclipse/e4/ui/bindings/EBindingService, have different Class objects for the type eclipse/jface/bindings/TriggerSequence;)Lorg/eclipse/jface/bindings/Binding; used in the signature
Hi, I have the same issue and also dosn't work the F3 key. My version is Juno 4.2. Thank you
Hi, same problem. Eclipse Standard/SDK Version: Kepler Service Release 2 Build id: 20140224-0627
What version did you update from? Did you have any other plugins installed? It sounds like you have two versions of org.eclipse.jface available. I'm not sure why they're both getting wired up. Could you please do the following to verify and help diagnose: 1. Open up the Console view. 2. Click on the "New Console" button in the view's toolbar and choose "Host OSGi Console"; this button is the on the far right with the little plus. Alternatively you can start Eclipse with the -console argument 3. At the "osgi>" prompt, type "ss org.eclipse.jface". You should see something like: osgi> ss org.eclipse.jface "Framework is launched." id State Bundle 341 ACTIVE org.eclipse.jface_3.10.0.v20140303-1751 342 RESOLVED org.eclipse.jface.databinding_1.6.200.v20140214-0004 343 RESOLVED org.eclipse.jface.text_3.9.0.v20131210-1348 359 ACTIVE org.eclipse.jface_3.XXXX Note the ids of the two org.eclipse.jface_* bundles (341 and 359 in the case above). 4. For each bundle id, use "inspect capability ID" where ID is the bundle id above. This will show the dependencies of each bundle. osgi> inspect bundle capability 341 org.eclipse.jface_3.10.0.v20140303-1751 [341] is required by: ------------------------------------------------------------- org.eclipse.ui.ide.application_1.0.500.v20140210-1835 [409] org.eclipse.wb.core.databinding_1.6.1.r44x201309092318 [430] org.eclipse.wb.core.ui_1.6.1.r44x201309092325 [433] One of them will have lots of dependencies. The other probably won't. 5. Copy and paste the output of the above here.
Note to self: org.eclipse.ui.workbench does a Require-Bundle of org.eclipse.jface org.eclipse.e4.ui.bindings does an Import-Package of org.eclipse.jface.bindings, org.eclipse.jface.binding.keys, org.eclipse.jface.binding.keys.formatting.
(In reply to Brian de Alwis from comment #5) I did the update to Luna release today and have now the same issue. Here's the requested information. I hope it helps because this issue is really annoying.

Thanks to Brian for the instructions, and removing the bundle of dependent of "Nothing" out of ECLIPSE/plugins solved the problem. Hopefully that can be a work-around for many people. FWIW, I observed the same problem once updated from 4.4 to 4.4.1 on Linux x64, Exceptions were observed within WORK_SPACE/.log Actually, many editing didn't work, not even "Find/Replace...", which was not just annoying :-(

I found that I had duplicate jface plugins from previous versions of the platform (due to upgrades). I moved the following plugins out of the plugins directory: org.eclipse.jface.databinding.source_1.6.200.v20140528-1422.jar org.eclipse.jface.databinding_1.4.0.I20100601-0800.jar org.eclipse.jface.databinding_1.5.0.I20100907-0800.jar org.eclipse.jface.text_3.6.1.r361_v20100825-0800.jar org.eclipse.jface.text_3.7.2.v20111213-1208.jar org.eclipse.jface_3.6.2.M20110210-1200.jar org.eclipse.jface_3.7.0.v20110928-1505.jar Then I restarted Eclipse and all was fine. After reading this bug, I moved the plugins back and went to the OSGI console but the problem was not happening again. Inspect showed: id State Bundle 292 RESOLVED org.eclipse.jface.databinding_1.6.200.v20140528-1422 545 ACTIVE org.eclipse.jface_3.10.1.v20140813-1009 546 RESOLVED org.eclipse.jface.text_3.9.1.v20140827-1810 583 STARTING org.eclipse.jface_3.7.0.v20110928-1505 584 STARTING org.eclipse.jface_3.6.2.M20110210-1200 585 RESOLVED org.eclipse.jface.databinding_1.5.0.I20100907-0800 586 RESOLVED org.eclipse.jface.databinding_1.4.0.I20100601-0800 587 RESOLVED org.eclipse.jface.text_3.7.2.v20111213-1208 588 RESOLVED org.eclipse.jface.text_3.6.1.r361_v20100825-0800 So, is this normal that after a version upgrade multiple plugins will be left active and cause this problem? I don't see a good way to remove duplicate and old plugins as you can't uninstall them via the Installation Default.
It's probably hard to find out how exactly the affected users ended up in a state where they had two active org.eclipse.jface bundles. I think the best solution is to just acknowledge that org.eclipse.jface is a singleton in practice. I.e. change MANIFEST.MF to: Bundle-SymbolicName: org.eclipse.jface;singleton:=true

I've only glanced at the details, but was just wondering if it'd help to have a tighter "lower bound" when pre-reqs specified? Or, maybe you'll need both? [And, again, just speculating ... hard for me to read error messages.]

(In reply to David Williams from comment #13) > You are probably right ... but, I wonder if this would just result in "the > lowest" one being loaded", at times, instead of the most recent? If singleton:=true is defined only one bundle is installed by the OSGi runtime, the deployment of the second bundle will fail (I asked Neil Bartlett, OSGi expert) about this.

I think that's pretty clear, Lars. Did he say it would always be "the right one"? :) While I would be the last to know, for this case, you could be solving one problem, but causing others. As one *possibility* an "update" from some of these old versions, to Luna, may not be possible? (From my brief reading, it seems to occur only when updating?) And, with p2's magic "conflict resolution" it has been known to "back level" items to make them fit ... if the user is not paying attention and/or is unwilling to "cancel" and would rather take their chances. And, don't get me wrong, ... I am only just suggesting this be well understood before taking what seems like an easy fix. Perhaps "singleton" is the right fix. But, in my mind, this is a "wiring" problem ... usually best fixed by proper constraints and/or "uses" clauses, whereas are singletons primarily for cases where there is a "fixed resource", that has to be shared. (And, I suspect, unrelated to "update") ... i.e. if really *had* to be a singleton, you'd see it with a fresh install as much as with an updated install, IMHO.
(In reply to David Williams from comment #16) > While I would be the last to know, for this case, you could be solving one > problem, but causing others..... We have several existing singletons in platform, i.e.g every plug-ins which defines extensions, so any problem related to that we already have. > And, don't get me wrong, ...

Dani, Markus, please advice if it is OK to mark jface as singleton.

When I upgraded Eclipse Luna from SR1 to SR2 with "Check for Updates" menu, I faced a very similar issue that logged the following error in .metadata/.log. java.lang.LinkageError: loader constraint violation: when resolving interface method "org.eclipse.e4.ui.bindings.EBindingService.getBestSequenceFor(Lorg/eclipse/core/commands/ParameterizedCommand;)Lorg/eclipse/jface/bindings/TriggerSequence;" the class loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) of the current class, org/eclipse/ui/internal/keys/BindingService, and the class loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) for the method's defining class, org/eclipse/e4/ui/bindings/EBindingService, have different Class objects for the type org/eclipse/jface/bindings/TriggerSequence used in the signature at org.eclipse.ui.internal.keys.BindingService.getBestActiveBindingFormattedFor(BindingService.java:232) at org.eclipse.jdt.ui.actions.OpenViewActionGroup.getShowInMenuLabel(OpenViewActionGroup.java:287) at org.eclipse.jdt.ui.actions.OpenViewActionGroup.fillContextMenu(OpenViewActionGroup.java:271) (snip) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:603) at org.eclipse.equinox.launcher.Main.run(Main.java:1465) at org.eclipse.equinox.launcher.Main.main(Main.java:1438) The workaround for me was that exiting Eclipse and restarting it with "-clean" command line option once.
