I also notice a full workspace build every time, why is this happening and how can it be fixed?

Comment 4 Dani Megert

2018-07-26 10:38:35 EDT

Can you check whether it works using 4.7.3a?

The fix for bug 522096 might be the culprit here.

Comment 5 Markus S

2018-07-26 15:19:37 EDT

Just found out that the issue does not occur in case I close the "Project Explorer" view before closing Eclipse!
It also does not trigger a full workspace build after restart in that case.


Regarding 4.7.3a, it would take quite some time to setup a new workspace with my projects so I hope the information I just gave you is enough to solve the problem.

Comment 6 Andrey Loskutov

2018-07-26 15:23:49 EDT

Just curious : how many projects/working sets do you have?

Comment 7 Markus S

2018-07-26 15:25:32 EDT

1100 projects, no working sets.

@Markus to test/fix this issue without changing your eclipse edition, here is a replacement jar with the fix. Don't know if this will work across linux to windows though?

Thread Dump after 10 minutes

I applied your plugin and it works as expected. The UI now does not freeze anymore after starting the IDE even with the Project Explorer view - thank you so much for this quick fix!

However, the "Initialize Java Tooling" job is now running for the exact same time like the UI was freezing before, so I still have to wait for this job to complete before I can start using the IDE.

Based on the thread dump it has to wait for the "Updating workspace" job to be completed, where it seems like it refreshing the whole workspace after startup (which is not what I want anyway).

Stack trace reminds me on bug 536918. Do you use maven tooling? Any errors in the log on startup? 

Please note, we recently fixed a bug where workspace build was always triggered on startup, may be is this related? Anyway, we will merge the patch from Lucas today, so with some luck next nightly 4.9 build would contain both fixes.

If this is by design, I wonder if it is a good design to init all containers *3 times in parallel*?

Comment 14 Andrey Loskutov

2018-07-27 17:27:26 EDT

Probably this *is* related to the bug 536990: two threads are running  SetContainerOperation and the third one is triggered on DeltaProcessor.resourceChanged, coming probably from the same SetContainerOperation. 

Those classpath changes triggered by SetContainerOperation were caused by a problem in access rules storage, see bug 536990 comment 23. In 4.8 we triggered build on almost *every* project on startup.

Markus: if I'm right, you should not see the problem anymore with the latest 4.9 nightly, for example http://download.eclipse.org/eclipse/downloads/drops4/I20180726-2000/ (which does *not* have a fix from Lucas yet, but for bug 536990).

Can you try it?

Comment 16 Markus S

Unfortunately I did not have the time to setup a 4.9 workspace, I will try to test this this week.

I tried the version you provided and everything seems to be working fine, as before with 4.6: the IDE is ready after 1 minute.

It does run a "quick" full workspace build however judging by the progress monitor description this is only reading the delta state on each project and does not do anything else, so this should be fine.

Thank you again!!

Thanks Markus, let close this one as fixed.

Please if you see the problem again, create a new bug for that.
