Description Edzard Egberts CLA 2007-07-02 13:03:39 EDT 
When trying to import a project of version 3 into new CDT version 4, the import hangs and CDT doesn't react any more. There is no CPU activity or memory allocation going on.

Thanks for the thread dump.

A deadlock happens between the threads "ModalContext" and "main".
While the ModalContext thread holds a lock on the ManagedBuildManager class, it tries to do a Display.syncExec() while the main thread is waiting to lock the ManagedBuildManager class and thus the syncExec can never complete.

Assigning to cdt-build for comment.

Thanks for looking into this, Anton. Yes, the bug is caused by the MBS project conversion mechanism. I'll have a look at fixing this for the 4.0.1

I really would like to, but I don't know, how to get a windows binary to verify? Is there a place to find pre-releases?

CDT 4.01 did the job and took the old configuration without problems. Thank you!
