Issue summary ------------- #ClassFileModuleName --- The name of a module is not a simple UTF-8 string but is, rather, derived from the value of the `this_class` field of the `ClassFile` structure, which is awkward. [1] Proposal -------- Revise the binary form of module declarations [2] as follows: - Add a `u2 module_name_index` field to the `Module` class-file attribute, immediately preceding the existing `module_flags` field. The value of this field will be the index of a `CONSTANT_Utf8_info` structure in the constant pool that represents the module's name in internal form, i.e., with period characters replaced by slashes [3]. - Rather than encode the module's name in the value of the `this_class` field of the `ClassFile` structure, simply set this field to zero. (Side note: The prototype implementation does not store module names in internal form, even though the draft specification [2] has long mandated that. The implementation will be fixed.)
