Method o.n.api.project.FileOwnerQuery.getOwner() is called in EDT after changed selection in File Chooser (o.n.m.project.ant.FileChooserAccessory.propertyChange()).

But the actual slowness is caused mainly by slow filesystem. The system was probably under heavy load, so resolving as WONTFIX may be valid.

Reassigning to projects/Ant. Tomas, please evaluate. Thanks.

This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue.

Thanks for your cooperation,
