j2ee related data loader/data object  should not care what project is belongs to.
reassigning.

the other dump is related to css(web component), I recall splitting both cases from a generic projects issue, but they got somehow merged again here. So there's at least a number of other dumps for each of these cases somewhere out there in the exception reporter.

I'm not sure about the history of this issue. I went through the latest 5 snapshots. Four of them are related to Maven project loading. One of them looks like slow filesystem (native calls being slow). Reassigning.

ProjectManager.findProject might block or might have to load a project which can take some time ... calling it in awt should be avoided

went through reports from 8.0.2 and filed separate issues to cover the particular cases - #252471, #252468, #252467, #252466, #252465, #252464, #252462, #252460
