Description dev2null 2007-07-24 15:18:53 EDT

If Platform.endSplash() is called in the IApplication.start() method before the workbench is created a SWT No more handles exception may be thrown during Workbench instantiation and startup.

The Javadoc for org.eclipse.core.runtime.Platform states that: "A runtime 
 * exception might be thrown or incorrect result might be returned if a method 
 * from this class is called while Platform is not running.". 
 
 I therefore added a call to Platform.isRunning() to check if the platform was running. The result was true.
 
 The call to Platform.endSplash() brings down the splash screen as expected but  PlatformUI.createAndRunWorkbench() results in a crash . The code for he IApplication.start() method:
 
	public Object start(IApplicationContext context) {
		Display display = PlatformUI.createDisplay();
		try {
			boolean isRunning = Platform.isRunning();
			Platform.endSplash();
			MessageDialog.openInformation(null, "Hello",
					"Platform isRunning is " + isRunning);

			int returnCode = PlatformUI.createAndRunWorkbench(display,
					new ApplicationWorkbenchAdvisor());
			if (returnCode == PlatformUI.RETURN_RESTART) {
				return IApplication.EXIT_RESTART;
			}
			return IApplication.EXIT_OK;
		} finally {
			display.dispose();
		}
	}
