After starting Eclipse, I tried to expand a project in the Packages Explorer. The expansion was blocked so I got the blocked dialog. I clicked on the button to cancel the expansion and an exception was logged. First of all, I wouldn't expect that expanding a project would need to obtain a scheduling rule. I would expect it to show me what it can at the time and then refresh when additional information become available. Also, I wouldn't expect to get an exception logged for performing a cancel.

Here's the trace:
