Maybe a broken install? Can you start with a fresh download?

Hi,

I downloaded this install from eclipse download page and working with it almost a month. This exception occurred once. Why do you think this is a broken install?

Thanks,
Yevgeny

This type of error is often meaning that a resource is not found (or not readable). However, this doesn't seem to be the case here: I looked closer at the code and it rather looks like this this happened while shutting down: it tries to create an image registry without having a display. This would then be bug 250455. Could this be the case?

Hi, 

I am not sure, but it is possible that it occurred during shotdown. There was a period that after I tried to close eclipse, it was waiting for specific action to finish before closing.

Thanks,
Yevgeny
