+/**
+ * A layer of modules in the Java virtual machine.
+ *
+ * <p> A layer is created from a graph of modules in a {@link Configuration}
+ * and a function that maps each module to a {@link ClassLoader}.
+ * Creating a layer informs the Java virtual machine about the classes that
+ * may be loaded from the modules so that the Java virtual machine knows which
+ * module that each class is a member of. </p>
+ *
+ * <p> Creating a layer creates a {@link Module} object for each {@link
+ * ResolvedModule} in the configuration. For each resolved module that is
+ * {@link ResolvedModule#reads() read}, the {@code Module} {@link
+ * Module#canRead reads} the corresponding run-time {@code Module}, which may
+ * be in the same layer or a {@link #parents() parent} layer. </p>
+ *
+ * <p> The {@link #defineModulesWithOneLoader defineModulesWithOneLoader} and
+ * {@link #defineModulesWithManyLoaders defineModulesWithManyLoaders} methods
+ * provide convenient ways to create a module layer where all modules are
+ * mapped to a single class loader or where each module is mapped to its own
+ * class loader. The {@link #defineModules defineModules} method is for more
+ * advanced cases where modules are mapped to custom class loaders by means of
+ * a function specified to the method. Each of these methods has an instance
+ * and static variant. The instance methods create a layer with the receiver
+ * as the parent layer. The static methods are for more advanced cases where
+ * there can be more than one parent layer or where a {@link
+ * ModuleLayer.Controller Controller} is needed to control modules in the layer
+ * </p>
+ *
+ * <p> A Java virtual machine has at least one non-empty layer, the {@link
+ * #boot() boot} layer, that is created when the Java virtual machine is
+ * started. The boot layer contains module {@code java.base} and is the only
+ * layer in the Java virtual machine with a module named "{@code java.base}".
+ * The modules in the boot layer are mapped to the bootstrap class loader and
+ * other class loaders that are <a href="../ClassLoader.html#builtinLoaders">
+ * built-in</a> into the Java virtual machine. The boot layer will often be
+ * the {@link #parents() parent} when creating additional layers. </p>
+ *
+ * <p> Each {@code Module} in a layer is created so that it {@link
+ * Module#isExported(String) exports} and {@link Module#isOpen(String) opens}
+ * the packages described by its {@link ModuleDescriptor}. Qualified exports
+ * (where a package is exported to a set of target modules rather than all
+ * modules) are reified when creating the layer as follows: </p>
+ * <ul>
+ * <li> If module {@code X} exports a package to {@code Y}, and if the
+ * runtime {@code Module} {@code X} reads {@code Module} {@code Y}, then
+ * the package is exported to {@code Module} {@code Y} (which may be in
+ * the same layer as {@code X} or a parent layer). </li>
+ *
+ * <li> If module {@code X} exports a package to {@code Y}, and if the
+ * runtime {@code Module} {@code X} does not read {@code Y} then target
+ * {@code Y} is located as if by invoking {@link #findModule(String)
+ * findModule} to find the module in the layer or its parent layers. If
+ * {@code Y} is found then the package is exported to the instance of
+ * {@code Y} that was found. If {@code Y} is not found then the qualified
+ * export is ignored. </li>
+ * </ul>
+ *
+ * <p> Qualified opens are handled in same way as qualified exports. </p>
+ *
+ * <p> As when creating a {@code Configuration},
+ * {@link ModuleDescriptor#isAutomatic() automatic} modules receive special
+ * treatment when creating a layer. An automatic module is created in the
+ * Java virtual machine as a {@code Module} that reads every unnamed {@code
+ * Module} in the Java virtual machine. </p>
+ *
+ * <p> Unless otherwise specified, passing a {@code null} argument to a method
+ * in this class causes a {@link NullPointerException NullPointerException} to
+ * be thrown. </p>
+ *
+ * <h3> Example usage: </h3>
+ *
+ * <p> This example creates a configuration by resolving a module named
+ * "{@code myapp}" with the configuration for the boot layer as the parent. It
+ * then creates a new layer with the modules in this configuration. All modules
+ * are defined to the same class loader. </p>
+ *
+ * <pre>{@code
+ * ModuleFinder finder = ModuleFinder.of(dir1, dir2, dir3);
+ *
+ * ModuleLayer parent = ModuleLayer.boot();
+ *
+ * Configuration cf = parent.configuration().resolve(finder, ModuleFinder.of(), Set.of("myapp"));
+ *
+ * ClassLoader scl = ClassLoader.getSystemClassLoader();

-/**
- * A layer of modules in the Java virtual machine.
- *
- * <p> A layer is created from a graph of modules in a {@link Configuration}
- * and a function that maps each module to a {@link ClassLoader}.
- * Creating a layer informs the Java virtual machine about the classes that
- * may be loaded from the modules so that the Java virtual machine knows which
- * module that each class is a member of. </p>
- *
- * <p> Creating a layer creates a {@link Module} object for each {@link
- * ResolvedModule} in the configuration. For each resolved module that is
- * {@link ResolvedModule#reads() read}, the {@code Module} {@link
- * Module#canRead reads} the corresponding run-time {@code Module}, which may
- * be in the same layer or a {@link #parents() parent} layer. </p>
- *
- * <p> The {@link #defineModulesWithOneLoader defineModulesWithOneLoader} and
- * {@link #defineModulesWithManyLoaders defineModulesWithManyLoaders} methods
- * provide convenient ways to create a {@code Layer} where all modules are
- * mapped to a single class loader or where each module is mapped to its own
- * class loader. The {@link #defineModules defineModules} method is for more
- * advanced cases where modules are mapped to custom class loaders by means of
- * a function specified to the method. Each of these methods has an instance
- * and static variant. The instance methods create a layer with the receiver
- * as the parent layer. The static methods are for more advanced cases where
- * there can be more than one parent layer or where a {@link Layer.Controller
- * Controller} is needed to control modules in the layer. </p>
- *
- * <p> A Java virtual machine has at least one non-empty layer, the {@link
- * #boot() boot} layer, that is created when the Java virtual machine is
- * started. The boot layer contains module {@code java.base} and is the only
- * layer in the Java virtual machine with a module named "{@code java.base}".
- * The modules in the boot layer are mapped to the bootstrap class loader and
- * other class loaders that are <a href="../ClassLoader.html#builtinLoaders">
- * built-in</a> into the Java virtual machine. The boot layer will often be
- * the {@link #parents() parent} when creating additional layers. </p>
- *
- * <p> Each {@code Module} in a layer is created so that it {@link
- * Module#isExported(String) exports} and {@link Module#isOpen(String) opens}
- * the packages described by its {@link ModuleDescriptor}. Qualified exports
- * (where a package is exported to a set of target modules rather than all
- * modules) are reified when creating the layer as follows: </p>
- * <ul>
- * <li> If module {@code X} exports a package to {@code Y}, and if the
- * runtime {@code Module} {@code X} reads {@code Module} {@code Y}, then
- * the package is exported to {@code Module} {@code Y} (which may be in
- * the same layer as {@code X} or a parent layer). </li>
- *
- * <li> If module {@code X} exports a package to {@code Y}, and if the
- * runtime {@code Module} {@code X} does not read {@code Y} then target
- * {@code Y} is located as if by invoking {@link #findModule(String)
- * findModule} to find the module in the layer or its parent layers. If
- * {@code Y} is found then the package is exported to the instance of
- * {@code Y} that was found. If {@code Y} is not found then the qualified
- * export is ignored. </li>
- * </ul>
- *
- * <p> Qualified opens are handled in same way as qualified exports. </p>
- *
- * <p> As when creating a {@code Configuration},
- * {@link ModuleDescriptor#isAutomatic() automatic} modules receive special
- * treatment when creating a layer. An automatic module is created in the
- * Java virtual machine as a {@code Module} that reads every unnamed {@code
- * Module} in the Java virtual machine. </p>
- *
- * <p> Unless otherwise specified, passing a {@code null} argument to a method
- * in this class causes a {@link NullPointerException NullPointerException} to
- * be thrown. </p>
- *
- * <h3> Example usage: </h3>
- *
- * <p> This example creates a configuration by resolving a module named
- * "{@code myapp}" with the configuration for the boot layer as the parent. It
- * then creates a new layer with the modules in this configuration. All modules
- * are defined to the same class loader. </p>
- *
- * <pre>{@code
- * ModuleFinder finder = ModuleFinder.of(dir1, dir2, dir3);
- *
- * Layer parent = Layer.boot();
- *
- * Configuration cf = parent.configuration().resolve(finder, ModuleFinder.of(), Set.of("myapp"));
- *
- * ClassLoader scl = ClassLoader.getSystemClassLoader();
- *
- * Layer layer = parent.defineModulesWithOneLoader(cf, scl);
- *
