Can you download the fullstack installer and use that to setup MyEclipse to a brand new location. Does MyEclipse start without errors now ?
trekmbikes - Sep 11, 2007 - 08:43 AM
Post subject: same
I'm getting the same error, and so are a lot of other people. I installed the bundle pack from the MyEclipse website, and started eclipse with the -clean option. The only other plugin I have is the latest Subclipse plugin. When I disabled either the MyEclipse plugins, or the SubClipse plugin, the problem goes away. I'm not sure which side of the fence the problem lies on.
trekmbikes - Sep 11, 2007 - 05:30 PM
Post subject: RE: same
I was wrong when I thought disabling Subclipse fixed the problem - it turns out this error starts only after I try to run Tomcat 6 from within MyEclipse. After Tomcat begins (and any time after that, including after you've stopped it), this annoying window pops up which totally prevents you from using Eclipse, and the same stack trace as above appears.

Post subject: Very annoying
I had this error too, very, very annoying. Not only when running Tomcat 6, but also Tomcat 5, MyEclipse Tomcat 6, and Jetty 6. I have disabled all plugins and reactivated them one by one. Deactivation of the TestNG plugin seemed to help, but, sporadically (once every 1-2 days) these dialog boxes still pop up and repeatedly clutter the screen. This goes away with Eclipse restart.

I suspect it has something to do with deployment or validation of applications on the application Servers, because it appears only when or after starting/restarting a (app) server with MyEclipse.

To be clear: Eclipse starts up very fine ,without the error. The error comes later.

PS
While this NOW occurs only sporadically on my machine, a colleague of mine reported me that he updated today to Eclipse 3.3 and ME 6, and is receiving the absolutely same error dialog under same circumstances. He hasn't ever installed TestNG plugin.

PPS
Here the screenshots I made two weeks ago, when it was really show stopping for me:

The message "Update Progress" is very strange and might be the hint.

vict0r,
This usually happens when the workspace gets corrupted. Can you switch to a workspace, create a new project and try working with it. Do you still run into this error ? If not, then you can import your projects from the old workspace into this new workspace and continue working.
vict0r - Oct 08, 2007 - 05:26 PM
Post subject:
Nipun,

I appreciate very much your support. Nevertheless, I'm not going to create a new workspace for this issue. I find it strange that everything worked fine until upgrading to E 3.3 and ME 6. And this happened not only to me, but also to my colleagues. Please note that we never share workspaces, only projects.
Maybe your standard answer is "workspace is corrupted, create a new one", but sorry, I did this often enough to know how tedious this is, and now I have so many projects and workspaces, that I'm not going to do this again without a clear and _simple_ path to copy most settings (Editor_s, Templates, Compiler, JDK's, Servers, etc) from one workspace to another.

vict0r,
Sorry about that, you are right that if -clean doesn't do the trick then normally a clean workspace atleast for testing a reproducible problem is a good next step.

Guys looking at the behaviors here alone:
1. Each user has a different plugin that "causes the problem", but disables it doesn't get rid of the problem completely.
2. Problem is somewhat random.
3. Complaints started with Eclipse 3.3

seems to suggest that this is a platform issue. You guys reported TestNG plugin, Subclipse and App server connectors all as causes in this thread... I'm really thinking this might be a platform snaffu.


Out of curiosity does *Everyone* get the incredible amount of

I get this error as well, I have rebuild my workspace, installed the regular installer and the full stack installer, rebuild my workspaces. All to no avail. See the same stack trace in my logs at time of occurence, all the exact same symptoms as vict0r.

Post subject: RE: Update Progress error
Thanks guys for the clarification.

I've been digging through the eclipse bugs and I can't find anything definitive BUT errors like this have been reported since version 2.0 and it seems certain behaviors can trigger it (like clicking package explorer/etc.)

Could you guys go to Window > Show View > Other... and open the Error Log view, then clear it, and as you work see if you can find a reproducable set of actions (like focusing a project, autocomplete in the editor, etc.) that causes this exception to get logged?

BTW I can't reproduce this on my end, so it's not like I'm just trying to keep you busy, I need a way to reproduce this.

We have had reports of incompatabilities with that version of Eclipse, as opposed to using the Eclipse "Classic" download. You might try reinstalling with that *or* just using the MyEclipse All in One installer which will install everything for you right out of the box.

Sorry for the trouble.

When I installed the FullStack install of ME6, it was extremely memory hungry...not sure what that was about though.

I'm going to uninstall ME6 and go back to 5 and see what happens....

It might have just "looked" that way because the default memory args allow a heap of 512mb before GC sets in. You can trim that down if you want.

No actually:
Eclipse 3.2.2 = MyEclipse 5.5.1
Eclipse 3.3 = MyEclipse 6.0
Eclipse 3.3.1 = MyEclipse 6.0.1 (coming out soon)

Were you able to find a case that reproduced the issue ever time? We are tracking it but so far do not have a reproducable test case and in *most* of our log files don't even get this exception. There seems to be some issue with certain setups that make the exception occur like crazy, but we haven't gotten much progress in the way of finding what it is.

Which platform are you on and which plugins do you add to your MyEclipse install?
vict0r - Oct 15, 2007 - 09:48 PM
Post subject:
I had freshly installed Eclipse 3.3 classic (the 140 MB package, see http://www.eclipse.org/downloads/moreinfo/compare.php) with ME 6.

Three weeks ago I thought it was TestNG's fault, because after uninstalling it the errors became only sporadic. Last week I reinstalled the TestNG plugin without additional side effects. But today afternoon I had again to restart Eclipse. The issues started when I shut down a Jetty engine. This mostly occured when shutting down/restarting/killing a app server / engine.

Another feeling I have: it might be related to network/proxy issues. Tree weeks ago I acted in a corporate LAN (with HTTP-only proxy), but the past two weeks I was only in my home office with transparent NAT. Today afternoon I had switched from WLAN to LAN some couples of minutes before the dialog boxes started to pop up. After Eclipse restart every thing went fine.

Summary:
- Eclipse started, running ok for some hours; Jetty engine running with ME;
- Switched on LAN interface and switched off WLAN interface;
- some couples of minutes later: shutdown Jetty;
- more and more error dialog boxes appeared => I restarted Eclipse

Using the MyEclipse Jetty Connector? If so, which version? 5/6?


Also very interesting find with respect to the network settings... it's possible that could be effecting it.

Are there certain network-enabled features that when used with the new network setup cause the exceptions? Like the Ajax Web Browser?

No Ajax Web Browser. Just plain Java/Servlet/JSP/HTML stuff (ok, wingsframework, but this is pure Java, and not browsing from within Eclipse).

Hi,

I just would like to report a "me too" here. I'm using Windows XP with the latest version of MyEclipse and Eclipse. I originally installed MyEclipse 6M1 and later on upgraded to MyEclipse 6GA and 6.0.1.The impression I get is that this particular error occurs whenever I do too many things at the same time; e.g. like updating a project from the SVN repository (using subversive) and while this update is taking place I start or restart Tomcat and before MyEclipse has really shown anything in the console I already that switching editors.

Normally I'm an easy going and thoughtful person ( :P), so the user interaction I sketched above does not happen very often. However, occasionally I'm into that behavior and it feels like the error happens then (although I can not reproduce it). A simple restart of Eclipse fixes the problem.

In my log I found a lot of these:

These are some of the settings that are printed in my log for the day the exceptions occured:

(the -clean apparently didn't help)

Till now the problem manifests itself only occasionally for me and I'm not *really* bothered by it. Nevertheless I hope this "me too" information is in someway helpful to you for solving the problem.

It does, it looks like it might just be a goofy UI call with relation to the progress dialog. Hopefully nothing too bad.

I faced the same problems in the last days. My feeling is similar, this only happens while running several tasks at the same time, and it seems to be related to the "progress" view which did not show running and waiting tasks properly. Today I imported a general eclipse configuration which is used on our project by many others, and this seems to fix the problem. I exported my configuration before, unfortunately I was not able to compare both configuration files.

If it is of interest, I can send those configuration files, if so please send a pm.

Guys, for the folks running into this issue, do you have the pre-6.0.1 hotfix installed? You can check by going to Help > Software Updates > Manage Configuration, and expanding the MyEclipse node and looking for it, it looks like this:

Another "me too" post on this.

I'll chime in with my observations... The first time I saw SWT-related problems seemed to correspond with problems synchronizing tasks from a remote Mylyn repository. Those errors immediately forced me to restart my workspace.

The "update progress" are no different than already described in this thread. The one difference is that it seems to happen shortly after I get a WOWEXEC error that the Windows 16-bit subsystem has run out of memory and I should reboot. Needless to say, I ignore their advice.

Anyone else seeing the WOWEXEC error before this problem begins?

Out of curiosity, is everyone seeing this *after* an upgrade using the update manager?

We are trying to dig out details that might allow us to pin point what is going on.
I've gotten the same error message in the past. Each time I had to start a new workspace. What a nuisance. I'm now getting the error message again. From all the posts, it seems we all have in common the subclipse plugin. Apart from the base installation of 6.01, I've installed the Mylyn, Jetty Launcher and Maven2 plugins. It seems to crop up after a few months of development. I do not want to have to recreate my workspace again if I can avoid it. Has a solution to this issue been found?


btw, I've tried starting up eclipse with "-clean" several times now and no help. It may have made it worse as I'm getting errors more frequently now.

Thanks,
Michael Nguyen

Here is my error log output of the last error message I just received:

I ran the update manager and found that during the entire process I received errors. When the process finished I received this display when selecting the only update required.

I installed myEclipse using the FullStack Installer. How could I be missing files if I have all the updates minus this one?

Here is the screenshot of the message

Michael,
If you go to Help > Software Update > Manage Configuration, and expand the node for MyEclipse, do you see the "Hotfix" installed?

I had met the same error.I think I solved the problem by below method.
a)close myeclipse
b)delete "last.config.stamp" which is in "%MYECLIPSE_HOME%eclipse\configuration\org.eclipse.update"
c)restart myeclipse ("last.config.stamp" will be recreated)
then there are no error again.
If the issue happen again, just redo that.
