NoSuchElementException during java binding generation from yang model with choice in module body at top level

BindingGeneratorImpl fails during java source code generation from yang model witch contains choice element directly in module body at top level.

For an example:
module choice-test {
yang-version 1;
namespace "uri:choice-test";
prefix tst;

revision 2014-10-07

{ description "Choice test."; }

choice my-choice {
case one {
leaf my-choice-leaf-one

{ type string; }

}
case two {
leaf my-choice-leaf-two

{ type int16; }

}
}
}

This is because the line 1213 and 1214 in BindingGeneratorImpl.java class:
final SchemaPath nodeSp = choiceNode.getPath();
final Object parentNode = findDataSchemaNode(schemaContext, nodeSp.getParent());

The parent path of choice element is empty (because parent is module) and therefore iterator.next() on the path fails.
