in AWT o.n.m.j2ee.p.e.h.NamedQueryHyperlinkProvider.getIdentifierSpan() -> FileOwnerQuery.getOwner()

where FOQ is being blocked by a concurrent project open. Unfortunately there is
nothing we can do about it on project side
please evaluate if there is a chance to invoke the call outside of awt or do not invoke the call in scope of .getIS() and instead check for projects asynchronoulsy when hyperlink is clicked
feel free to close otherwise
thanks
