Description Dominik äger CLA 2011-10-02 05:25:45 EDT 
Build Identifier: 20110615-0604

Internal errors occur in org.eclipse.equinox.internal.p2.artifact.repository during the update process started by Help -> Check for Updates. The update is "Eclipse IDE for C/C++ Developers version 1.4.1.20110909-1818". The errors cause the update to fail. The .log file shows a different buildId (20110613-1736) than the About Eclipse dialog (20110615-0604) which I find strange. I was able to reproduce everything with a freshly downloaded installation and empty workspace, also making sure that I had the right .log file. The buildId of the About Eclipse dialog was the same before and after the failed update.
The .log file is attached for details.

Reproducible: Always

Steps to Reproduce:
1. Get the current Eclipse IDE for C/C++ Developers (includes Incubating components) Indigo Package (20110615-0604)
2. Start eclipse in new empty workspace
3. Select Help -> Check for Updates
4. Try to install the Eclipse IDE for C/C++ Developers version 1.4.1.20110909-1818 update.
5. Wait for errors to occur.

This is an issue with Java 7. This has been addressed in SR1
