Old launch configurations don't switch perspectives automatically

Because of the internal data structure changes, launch configurations created with an older version of the IDE won't automatically switch to the Debug perspective when used as a debug configuration.
To fix this problem:
  1. Choose Run > Debug… to open the Debug configuration dialog.
  2. Change any of the settings for this launch configuration, then click Apply to save the change.
  3. Change the setting back to the way you had it before, then click OK to revert your change and close the dialog.
