I am on the 5.0.3 version and yesterday, I could launch the TOS on the branch with no problem.
Does anyone already have this error ? Do you have any ideas ofr a solution ? 
Thanks

Hi
5.0.3 was an rather old version, what's your JDK version? Can you please upload log messages which are located in <studio install dir>/workspace/.metadata/.log

Thanks for your reply,
I know that 5.0.3 is an old version but for the moment, it's the version the client is using... 
The JDK version is the 1.7 
I put the log messages in the attachment.

Hi pdenis
5.0.3 does not support JDK 1.7, 1.6 is recommended JDK version. I would suggest you to downgrade JDK version, if the problem still exists, follow the steps to resolve it:
1. Back up your local workspace.
2. Delete the workspace folder. 
3. Restart talend enterprise studio, it will check out the project from svn server to local workspace again.

Hello,
I met the same problem and I solved it by this way :
- checkout out the working branch with Eclipse
- go the metadata folder in the branch
- watch for the last modified files
- delete the last modified files
- commit the deletion (under Eclipse)
- launch the TOS
and it was Ok.
