The piece of the jcod file with the defect:

module {
  0xCAFEBABE;
  0; // minor version
  53; // version
  [13] { // Constant Pool
    ; // first element is empty
    class #9; // #1 at 0x0A
    Utf8 "SourceFile"; // #2 at 0x0D
    Utf8 "module-info.java"; // #3 at 0x1A
    Utf8 "Module"; // #4 at 0x2D
    Module #10; // #5 at 0x36
    Module #11; // #6 at 0x39
    Utf8 "9-ea"; // #7 at 0x3C
    Module #12; // #8 at 0x43
    Utf8 "module-info"; // #9 at 0x46
    Utf8 "modAccessControl00101m037.ma"; // #10 at 0x54
    Utf8 "java.base"; // #11 at 0x73
    Utf8 "modAccessControl00101m037.mt"; // #12 at 0x7F
  } // Constant Pool
....
    Attr(#4, 28) { // Module at 0xB4
>> #10; // name_index : modAccessControl00101m037.ma
      0x0000; // flags
      #0; // version

The correct line should be:

 Attr(#4, 28) { // Module at 0xB4
>> #5; // name_index : modAccessControl00101m037.ma
      0x0000; // flags
      #0; // version

Module_name_index - the constant_entry at that index must be a CONSTANT_Module_info structure bu there it is Utf8
