der,
Thank you for the heads up, we are going to do a bit more investigation on our part first.

Crosslink to a possible reason(?): 6.0.0 hotfix not uninstalled by 6.0.1 update .

I'm running full stack install Build id: 6.0.1-GA-200710 on Vista Business and I also get this error once in a while, but lately it has been happening more and more.

Stacktrace is:

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:

I do have that hotfix installed, and still have the problem as well.

Can you try disabling the hotfix and restarting? It should have been integrated into 6.0.1 anyway. This may correct the issue.

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?

- Jack

Jack,
I haven't seen that issue before... but did disabling the hot fix help get rid of the SWTExceptions?

Hmm... so things improved? 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

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.
