Build Identifier: 20100617-1415 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 Error: attempt to set description for a project which does not exist or not

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 Reproducible: Couldn't Reproduce Steps to Reproduce: Happened once, cannot reproduce it again.
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
