 * <p>One path type is handled in a special way: unlike other options,
 * the paths specified in a {@code --patch-module} Java option is effective only for a specified module.
 * This type is created by calls to {@link #patchModule(String)} and a new instance must be created for
 * every module to patch.</p>
 *
 * <p>Path types are often exclusive. For example, a dependency should not be both on the Java class-path
 * and on the Java module-path.</p>
