Bug 2333 - Java code generation error, when yang model contains Choice node
in module body at top level
BindingGeneratorImpl fails (NoSuchElementException) during java source code
generation from yang model which contains Choice node directly in module body
at top level. The parent path of Choice node is empty (because the parent
is the module) and therefore iterator.next() on the path fails. For more
information see Bug 2333.
