The Throwable just results in is a boilerplate code block like the following that does not actually require handling of the runtime errors: | try | { | kernelDeployer = new BasicXMLDeployer(context.getKernel()); | } | catch(Error e) | { | throw e; | } | catch(Exception e) | { | throw e; | } | catch(Throwable e) | { | // Should not happen | throw new Exception("Failed to create BasicXMLDeployer", e); | } | This still does not really solve the problem you are after as I have ignored the runtime exceptions/errors as before. It seems what we really need is a KernelAction wrapper similar to a PriviledgedAction that integrates with the caller's kernel state to ensure exceptions are properly reflected in the state machine. I don't see how to force use of this though. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3957429#...
