Hello
I’ve recently upgrade to CodeMix 3.0 from Webclipse, but I’m experiencing an important problem: after some time working (a couple of hours on an Angular 5 project) it starts consuming a lot of CPU, even if I stop doing something on the IDE. The processes called Code Mix Engine suddenly start to work hard but don’t know what they are doing. The result is the code assistant stop working, the IDE is almost stuck, NodeJs server is shut down and can’t restart anymore.
I have to close and reopen Eclipse to fix it, but it happened 3 times yesterday and even today.
The only error I see in workspace is the following:
java.lang.NoClassDefFoundError: org/objectweb/asm/ClassVisitor (occurred in org.eclipse.xtext.ui.shared.internal.ExecutableExtensionFactory)

Same workspace never had this issue before migrating to CodeMix.

Please help, I had been working with WebClipse for a couple of years and it was good, now I’m struggling.
Thanks
Regards

Sorry to hear you’re running into this – certainly should not be happening. We’ve noticed that in some cases, some of the Code Mining support may be causing performance issues. This is why it’s typically off by default, but it may be on in your case.

1) Turn off Code Mining from Preferences > Editors > Code Mining – ensure all the checkboxes are unchecked.
2) Restart Eclipse.
3) If you still run into the issue, or Code Mining was already off, please reach out to us via Live Chat (Help > CodeMix > Live Chat) where we can debug this live with some diagnostic tools.

Thanks, and apologies again for the disruptions – hopefully we’ll be able to knock this out in short order.

Hello Brian
I’ve just verified and they are all unchecked, today I’ve worked on Java code mainly (server side of our application) and IDE has been working fine so far. I suppose it is the Angular part that is causing the problem. Thanks for your support, when it will happens next time I’ll contact you on chat.

Regards

Giovanni,

Thank you for the update. Would be good to know what editors you’re using when you run into the problem – I guess it will be both the TypeScript editor and the HTML editor for Angular templates?

[GIOVANNI]

Hello
It happened this morning again and I’m quite sure it is the TypeScript editor. I had to restart Eclipse as I needed to finish that piece of code, now I’m going to work on it. I will open chat as soon as CPU reaches high values.
Thanks

Hi,
I am experiencing the same issue as well.
The CodeMix engine disconnects and I can’t even save the changes I’ve made in the Typescript files afterwards.
The only thing I can do is restart Eclipse.
This has happened at least 3 times today for me.

Versions info:
– Codemix 3 Release CI 2019.6.19 (Commercial Licence)
– Eclipse IDE for Enterprise Java Developers – Version: 2019-03 (4.11.0), Build id: 20190314-1200

I would be grateful for any advice as this is really hindering my productivity.

Many thanks

[Brian Fernandes]

Glen,

Sorry to hear you’re running into this. This is an extremely high priority issue but we’ve been unable to reproduce it internally so far. I’m assuming you’ve already checked the Code Mining settings I mentioned above?

If you could come in to a Live Chat session when you experience the issue, we’d greatly appreciate it as that would help us diagnose it and get a fix in ASAP.

[glen_jai]

This has just happened.
As suggested by your support last time I was on Live Chat, here is are relevant parts of my Eclipse .log file just after it happened.

!ENTRY com.genuitec.eclipse.code.core 1 0 2019-07-10 17:17:47.594
!MESSAGE Detected orphaned CodeMix engine processes; cleaning up.

!ENTRY com.genuitec.eclipse.code.core 4 0 2019-07-10 17:17:53.466
!MESSAGE Succeed to restart CodeMix Engine after 1 attempt(s).

I should mention that it may have been caused by an earlier problem, whereby the Angular Dev Server threw an error due compilation problem. Afterwards it just hung, and I wasn’t able to stop it in the terminal. So I ended up closing the terminal and opening a new one to start another Dev server instance.

Not sure if this issue was meant to be fixed, but the CodeMix engine just restarted again on my Eclipse.
As before it has hung the Eclipse terminals so needed a restart.

Relevant parts of my Eclipse .log file just after it happened.

Glen,

We did put out one important performance fix in the release that you area already on, that would most likely hit users as they edit source. This appears to have fixed that issue, as we have see no reports of the problem since the release went out (from 2-4 reports a week prior to that). The issue you are running into appears to be different.

CodeMix restarting the engine is normal/good as it allows you to continue working without having to kill or restart Eclipse. Of course, it should not have hung in the first place …

a) Is there anything you can share to help us reproduce the issue? Does it always happen when serving an Angular project, perhaps only if the project has an error? Have you seen it happen in any other circumstances?
b) I’m assuming the rest of Eclipse remains responsive, and you’re even able to start new terminals?
c) Can you please share with us the full log file so we can check for other diagnostic information?

Thanks!

[glen_jai]

Hi Brian,

Thank you for your response.
When the CodeMix engine restarts, I don’t seem to be able to save the files that are currently open.
I am not able to launch a new terminal.

I think it does only happen when an angular dev server is running.
Would rather not paste my log file on the forum, but happy to send to you via live chat or something.

Kind regards,
Glen

Hi Brian,

This has happened again today. I have attached a screenshot of the error message displayed in Eclipse.
Again, I am unable to start a new terminal or save changes on open files.

Tail end of Eclipse log as follows (error occured at 18:19 as per last logged message):

Glen,

Thank you for sending in the detail – unfortunately with the unique nature of this problem, we can’t tell anything from these logs, but obviously you are being affected by something serious.

Can you simply join a Live Chat the next time it happens (Help > CodeMix > Live Chat)? We can run some engine diagnostics when you are experiencing the problem and hopefully figure it out on the spot. We’re planning another release soon, so it would be great if we could get this fix in.

Thanks!
