public int getInnerNameIndex() {

If C is anonymous (JLS ?15.9.5), the value of the inner_name_index item must be zero.
<p>
Otherwise, the value of the inner_name_index item must be a valid index
into the constant_pool table, and the entry at that index must be a
CONSTANT_Utf8_info (?4.4.7) structure that represents the original simple
name of C, as given in the source code from which this class file was
compiled.
@return a valid index into the constant_pool table, or zero
