Hi Eric,

I used the latest version from the CVS and found the problem. It was in the wrong annotation file detection (https://bugs.eclipse.org/bugs/show_bug.cgi?id=236997). Now scenario you described works fine. I've also try to create more annotations, restart Eclipse and so on.

Best regards,
Yuri Strot.

Hmmm... For some reason the build I’m mentioning here does not want to
appear on the http://www.eclipse.org/tigerstripe/downloads.php page,
although I can see it when I ssh into the eclipse server directly.

Something seems different in the way the partitions are mounted on the
Eclipse webserver today.

I’ve contacted them for help.

Eric
