*** Bug 339314 has been marked as a duplicate of this bug. *** Likely to be two threads in the same weaver, which isn't reallllly supported, although Spring does it (but spring is only pointcut matching, not weaving). Let's see if any other users hit this, I can't immediately see the problem on a quick look. Actually, we (Scala IDE for Eclipse project) also experience this issue from time to time (the stacktrace look similar enough) Here is one of the possible stacktraces:

In our most recent testing around Eclipse 4.2 and 3.7.2 we have discovered some changes in equinox weaving have affected us. They removed some classloader locks around calling the weaving hooks that AspectJ weaving was relying on. Some changes were committed (in the last few days) into equinox weaving to add some new hooks at a different layer to deal with the problem. I'll ping Martin Lippert to respond here about specifics. As Andy mentions, these changes are already available in the snapshot versions of AJDT. Try updating to the latest snapshot of Equinox Weaving available from the AJDT update sites here: for Indigo http://download.eclipse.org/tools/ajdt/37/dev/update or for Juno http://download.eclipse.org/tools/ajdt/42/dev/update All you need to update is the Equinox Weaving feature. Hopefully, this will fix the problem. We were using the release stream for Eclipse 3.7 http://download.eclipse.org/tools/ajdt/37/update. Now I've updated it to use the dev stream. Thanks a lot to both of you for the quick turnaround. For future reference, here is the ticket related to this issue on our issue tracker: http://scala-ide-portfolio.assembla.com/spaces/scala-ide/tickets/1000941 Feel free to comment there if I forget to get back to you. Unfortunately, updating to the AJDT 3.7 dev stream didn't help, we still see the ConcurrentModificationException. Below are a few stacktraces of what I believe is the same error, hopefully they are helpful. 1) --------------------------------------------------------------- 2012-05-09 10:23:56,585 DEBUG [Thread-1]

Can we double check that version of equinox weaving you have ended up with? Help -> About Eclipse -> Installation details. Under my AJDT entry in the Installed Software tab, there is a: Equinox Weaving SDK 1.0.200.I20120427-0800 or on the plugins page there is an entry: pluginname: AspectJ Weaving Hooks Plug-in (incubation) Version 1.0.200.I20120427-800 Sure, that's what we have: AspectJ Weaving Hooks Plug-in (incubation) Version 1.0.100.v20110502 Which is an older than the one I believe we should have. But I'm a bit puzzled, isn't this dependency supposed to be taken from the AJDT p2 repository we build against? (i.e., http://download.eclipse.org/tools/ajdt/37/dev/update) Here is the POM were we declare the AJDT repo to use for building the Scala IDE: https://github.com/scala-ide/scala-ide/blob/master/org.scala-ide.build/pom.xml#L21 You are correct in that the version of AJDT you have installed is the older version and it is no longer available from the dev update site that you are using in your pom. I don't see how you could be getting that version right now. Could it be that you are using cached dependencies? Perhaps try nuking your m2 repository and try again. Yeah, right after writing my last comment I realized that we may have caching (maven mirrors set in our settings.xml). I can check this only on Monday, I'll keep you posted. Andrew, thanks a ton for your support, I really appreciate it. I can confirm we had a local mirror of the AJDT p2 repository, and that's why we were still linking against the old "AspectJ Weaving Hooks Plug-in" (again, sorry for the noise). We'll keep testing and I'll let you guys know if we still hit the ConcurrentModificationException issue. No ConcurrentModificationException in the Scala IDE builds for two weeks, I would consider this ticket fixed. Guys, thanks a lot for the follow up. This issue was *really* annoying, and now it is just gone. Good job. *** Bug 386024 has been marked as a duplicate of this bug. *** |
