> Unlike Java, JavaScript has not concept of a nested exception, so that means 
> intercepting an initialization exception so report it ultimately makes it 
> harder to debug:  even using a client debugger, there's no way to see the 
> origin of the exception (the way you would find a nested exception in Java), 
> and the error console output reporting the exception reports the stack trace 
> only up to the code that caught the exception and invoked t5.console.error(), 
> rather than the underlying exception.
