This logic allows the generated Java code to be easily translated to C# (via sharpen) -
as in C# 0 represents end of file, and in Java, -1 represents end of file
See : http://msdn.microsoft.com/en-us/library/9kstw824(v=vs.110).aspx
** Technically, this is not required for java but the overhead is extremely low compared to the code generation benefits.
