reloadConnections executing in UI thread can cause hang when switch to Docker Tooling perspective [EBZ#517143] -------------------------------------------------------------------------------------------------------------- Key: ERT-510 URL: https://issues.jboss.org/browse/ERT-510 Project: Eclipse Release Train Issue Type: Task Components: Linux Tools Reporter: Friendly Jira Robot Assignee: Roland Grunberg Labels: Docker, bzira Fix For: Oxygen (4.7) DockerConnectionManager.getInstance() will end up calling reloadConnections if the singleton has not yet been created (likely when a user opens the perspective for the first time). The call exists in various createControl() methods so the reloading of connections could take place under the UI thread. We should guard against this by having the logic execute under a background job that populates the Explorer view as it completes.
