             Summary: 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


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.
