-/**
- * root-ClassLoaderValue. Each instance defines a separate namespace for
- * associated values.
- * <p>
- * ClassLoaderValue allows associating a
- * {@link #computeIfAbsent(ClassLoader, BiFunction) computed} non-null value with
- * a {@code (ClassLoader, keys...)} tuple. The associated value, as well as the
- * keys are strongly reachable from the associated ClassLoader so care should be
- * taken to use such keys and values that only reference types resolvable from
- * the associated ClassLoader. Failing that, ClassLoader leaks are inevitable.
- * <p>
- * Example usage:
- * <pre>{@code
- * // create a root instance which represents a namespace and declares the type of
- * // associated values (Class instances in this example)
- * static final ClassLoaderValue<Class<?>> proxyClasses = new ClassLoaderValue<>();
- *
- * // create a compound key composed of a Module and a list of interfaces
- * Module module = ...;
- * List<Class<?>> interfaces = ...;
- * ClassLoaderValue<Class<?>>.Sub<Module>.Sub<List<Class<?>>> key =
- *     proxyClasses.sub(module).sub(interfaces);
- *
- * // use the compound key together with ClassLoader to lazily associate
- * // the value with tuple (loader, module, interfaces) and return it
- * ClassLoader loader = ...;
- * Class<?> proxyClass = key.computeIfAbsent(loader, (ld, ky) -> {
- *     List<Class<?>> intfcs = ky.key();
- *     Module m = ky.parent().key();
- *     Class<?> clazz = defineProxyClass(ld, m, intfcs);
- *     return clazz;
- * });
- * }</pre>
- * <p>
- * {@code classLoaderValue.<operation>(classLoader, ...)} represents an operation
- * to {@link #get}, {@link #putIfAbsent}, {@link #computeIfAbsent} or {@link #remove}
- * a value associated with a (classLoader, classLoaderValue) tuple. ClassLoader
- * instances and root-{@link ClassLoaderValue} instances are compared using
- * identity equality while {@link Sub sub}-ClassLoaderValue instances define
- * {@link #equals(Object) equality} in terms of equality of its
- * {@link Sub#parent() parent} ClassLoaderValue and its
- * {@link #key() key} component.
- *
- * @param <V> the type of value(s) associated with the root-ClassLoaderValue and
- *            all its {@link #sub(Object) descendants}.
