Improve BaseExplorerContentProvider.loadChildren() -------------------------------------------------- Key: JBIDE-21216 URL: https://issues.jboss.org/browse/JBIDE-21216 Project: Tools (JBoss Tools) Issue Type: Enhancement Components: openshift Affects Versions: 4.4.0.Alpha1 Reporter: Viacheslav Kabanovich Assignee: Viacheslav Kabanovich Labels: performance Fix For: 4.4.0.Alpha1 This method may be called concurrently while children for current parentElement are being loaded. Now for this case implementation calls directly getChildrenFor(parentElement) which loads children in ui thread. So, if by some reason loading children in a separate job took a lot of time, by the same reason this second call in ui thread may hang Eclipse for some time. Instead, it seams reasonable just to return the available loading stub as a child, when loading job is completed it will call refresh. [~adietish] please take a look at the pull request.
