Bug 58817 UI no longer responsive when sorting search matches
Build 20040413 I searched for references to type: java.lang.System in org.eclipse.jdt.core project. This found over 4000 matches. I attempted to sort them by parent name, and my IDE locked for about 5 minutes to do the work, with no progress indication, no refresh and 100% CPU usage. Clearly something to improve on UI responsiveness front.
