| * // is defined, and the System ClassLoader's unnamed module, |
| * // where MyDiffClassLoader is defined. This read edge |
| * // is needed before we can obtain MyDiffClassLoader.loader2's unnamed module. |
| * // |
| * // Step #2: Establish a read edge between m1x, where c3ReadEdgeDiffLoader |
| * // is defined, and the MyDiffClassLoader.loader2's unnamed module, |
| * // where c4 will be defined. |
| * |
| * // Step #1: read edge m1x -> System ClassLoader's unnamed module |
| * Module m1x = c3ReadEdgeDiffLoader.class.getModule(); |
| * ClassLoader system_loader = ClassLoader.getSystemClassLoader(); |
| * Module unnamed_module_one = system_loader.getUnnamedModule(); |
