Eclipse restart using 'PlatformUI.getWorkbench().restart()' is not restarting the RCP product

Question

Upon invoking the method PlatformUI.getWorkbench().restart() the application is simply closing and refusing to restart the product.

Answer 1

Your IApplication needs to check the return code from PlatformUI.createAndRunWorkbench in the start method:

The simplest is:

int returnCode = PlatformUI.createAndRunWorkbench(display, advisor);
if (returnCode == PlatformUI.RETURN_RESTART)
   return IApplication.EXIT_RESTART;

return IApplication.EXIT_OK;

More recent applications seem to use this:

private static final String SYSTEM_PROPERTY_EXIT_CODE = "eclipse.exitcode";

int returnCode = PlatformUI.createAndRunWorkbench(display, advisor);

if (returnCode == PlatformUI.RETURN_RESTART)
 {
   // eclipse.exitcode system property may be set to re-launch
   if (IApplication.EXIT_RELAUNCH.equals(Integer.getInteger(SYSTEM_PROPERTY_EXIT_CODE)))
      return IApplication.EXIT_RELAUNCH;

   return IApplication.EXIT_RESTART;
 }

return IApplication.EXIT_OK;
