Null contextClassLoader in swt app when started with splash-screen

Question

our application is a quite simple SWT app which was working fine until we started to run it with java option -splash:splashScreen.jpg. Since that moment there is no contextClassLoader ( Thread.currentThread().getContextClassLoader() ) available in AWT threads (AWT-EventQueue-0) (when we click on some button) and some of 3rd party libraries are not able to handle this:(

Java utilizes Bootstrap ClassLoader for -splash, therefore, EventQueue has its private final classLoader set to null - so is there some way how to drop whole AWT EventQueue and let it be created again? Or is there any other way how to convince AWT that there should be some contextClassLoader set?

Thanks
