Answer 1

You get a NullPointerException. This happens because you are using a reference which is null. In your case this is one of the fields in the line that you marked.

Use a debugger, put a breakpoint on that line, and inspect which field in null.

Answer 2

Since you use all the variables, only VGC can be null at this time.

But I suspect this is a class name. My first guess is that the type VGC is part of the server API and not of the client API or something along these lines.
