Hello Stanislav, In QA tests we see the following situation: toolbar with New Project is missed after IDE is started. And it is missed from the View -> Toolbars menu as well. This situations is not always reproducible, but in 100 tests runs we can always find this effect. It also can be reproduced on Ubuntu: multiple manual starting of IDE produces such effect (Valeriy can provide the details). Default logs do not contain any glue on the issue. Is there are any special logging that should be turned on to get more information on this? Regards, Igor
More exactly. I see such exception in messages.log: INFO [org.openide.loaders.FolderInstance.Toolbars]: Cannot create org.openide.loaders.FolderInstance$HoldInstance@229761[Toolbars/File] java.io.IOException: Cyclic reference. Somebody is trying to get value from FolderInstance (org.openide.awt.Toolbar$Folder) from the same thread that is processing the instance at org.openide.loaders.FolderInstance.instanceCreate(FolderInstance.java:299) at org.openide.loaders.FolderInstance.instanceForCookie(FolderInstance.java:580) at org.openide.loaders.FolderInstance$HoldInstance.instanceCreate(FolderInstance.java:1150) [catch] at org.openide.loaders.FolderInstance$1R.instances(FolderInstance.java:700) at org.openide.loaders.FolderInstance$1R.run(FolderInstance.java:721) at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:1432) at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:2042)
This issue probably belongs to component platform/Window System.

I see such exception in messages.log: Can you please attach your full IDE Log to the issue? It might be also helpful to have a thread dump, to see what's happening if the toolbar isn't initialized (http://wiki.netbeans.org/GenerateThreadDump). Thank you.

The logging can be turned on with this parameter: -J-Dorg.openide.loaders.FolderInstance.Toolbars.File.level=FINEST Which release do you use for testing? A custom build, or a development build downloaded from NetBeans web site (if so, which type [ZIP,installer] and bundle [full,C++])? Thank you.

(In reply to comment #9) > Created attachment 137072 [details] > NetBeans with -J-Dorg.openide.loaders.FolderInstance.Toolbars.File.level=FINEST Thank you very much for the log. It seems that three instances of toolbar defined in Toolbars/File were created (instead of just one instance), which leads to an illegal state. But unfortunately I cannot find why this happens. Can you please change the logging parameter to this one? Thanks. -J-Dorg.openide.loaders.FolderInstance.Toolbars.level=FINEST

I'm sorry, I haven't managed to create a test case for this bug yet. I've added some logging into FolderInstance: http://hg.netbeans.org/core-main/rev/690094c522d3 http://hg.netbeans.org/core-main/rev/4844fefb1ece Please attach a new messages.log after the changes are propagated. Thank you.
Integrated into 'main-silver', will be available in build *201307192300* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main-silver/rev/4844fefb1ece User: Jaroslav Havlin <jhavlin@netbeans.org> Log: #232389: FolderInstance.waitFinished - Log value of the local reference

Thank you for the new log. Unfortunately, all parts of the code that I suspected of causing the problem work correctly, and I haven't been able to reproduce the bug yet. I'll have to estimate which other parts could be problematic.

The bug appears during manual testing as well and it looks like a consequences of some races. I was able to reproduce the bug using a simple scenario: - run IDE with a fresh userdir - create a sample project then close it - close IDE - do run and close IDE with the same userdir several times After several attempts IDE starts without File toolbar.
I've sent a waiver request for this bug. It's difficult to debug, and fixing it would be probably quite risky. I would prefer to have much more time for testing changes in this area.

This doesn't cause the bug directly. I've temporarily changed the code so that the instances were duplicated artificially, and started NetBeans several times, but the bug didn't appear (Linux, OpenJDK 7u25). Creating duplicate instances for the same folder in a test case also worked well. (But duplicated instances may still be a necessary condition.)
http://hg.netbeans.org/core-main/rev/e9f8dd1301d7 Prevent creation of duplicate instances of Toolbar.Folder for single Toolbar. If the bug appears again, please attach new IDE Log. Thanks.
Can you still reproduce the bug with a recent daily build? If so, please attach new IDE Log (using -J-Dorg.openide.loaders.FolderInstance.Toolbars.level=FINEST). Thank you.
> If the bug appears again, please attach new IDE Log. Thanks. It seems that the problem has been solved. If not, please reopen this issue. Thank you very much for help.

I'm having this issue on NetBeans 8.2 Both on the IDE as well as a NB-Platform application.
