Hi,

I've been using eclipse 3.6 with CDT 7.0 for ~3 weeks now. I don't use automatic indexing, from time to time I invoke "Index->Update with Modified Files". Yesterday when doing this action eclipse "disappeared". I invoked it and got the following exception:
!ENTRY org.eclipse.core.resources 2 10035 2010-07-13 16:29:30.577
!MESSAGE The workspace exited with unsaved changes in the previous session; refreshing workspace to recover changes.

I tried to repeat "update with modified files" action but it did not do anything. I closed the c++ project and got the following exception:
!ENTRY org.eclipse.cdt.core 4 0 2010-07-13 16:33:48.270

!MESSAGE attempt to set description for a project which does not exist or not open

After reopening c++ project it started to reindex the project from scratch. 

I will be more than happy to provide any additional information that could help understand / solving this issue.

Thanks a lot,
Yevgeny

The 'disappearing' is your JVM crashing. Which JVM version is it? Is there an error log?

The exception is logged when an attempt to set the project description on a project which isn't accessible -- this isn't a fatal error in any way.

Hi,

yevgenys@yevgenys-lnx:~$java -version
java version "1.6.0_18"
OpenJDK Runtime Environment (IcedTea6 1.8) (6b18-1.8-0ubuntu1)
OpenJDK 64-Bit Server VM (build 14.0-b16, mixed mode)

Any ideas where I can find JVM crash log (I am running on linux Ubuntu)?

Thanks,
Yevgeny

Not sure I'm afraid.
Try `ulimit -c unlimited` before starting eclipse to generate a core file on crash.

Most Eclipse users use either a Sun VM or an IBM VM:
http://www.eclipse.org/projects/project-plan.php?planurl=http://www.eclipse.org/eclipse/development/plans/eclipse_project_plan_3_6.xml#target_environments

A JVM crash is not eclipse unless it's in one of our shared objects; feel free to re-open if you can pin this down to eclipse.

Hi,

Thanks for the quick reply. I'll try switching to SUN JDK. Unfortunately this issue happened again today, I am still not able to locate any log / core file.

Best regards,
Yevgeny
