+/**
+ * A Java method handle extends the basic method handle type with additional
+ * programmer defined methods and fields.
+ * Its behavior as a method handle is determined at instance creation time,
+ * by providing the new instance with an "entry point" method handle
+ * to handle calls. This entry point must accept a leading argument
+ * whose type is the Java method handle itself or a supertype, and the
+ * entry point is always called with the Java method handle itself as
+ * the first argument. This is similar to ordinary virtual methods, which also
+ * accept the receiver object {@code this} as an implicit leading argument.
+ * The {@code MethodType} of the Java method handle is the same as that
+ * of the entry point method handle, with the leading parameter type
+ * omitted.
+ * <p>
+ * Here is an example of usage:
+ * <p><blockquote><pre>
+ * class Greeter extends JavaMethodHandle {
+ * public void run() { System.out.println("hello, "+greetee); }
+ * private final String greetee;
+ * Greeter(String greetee) {
+ * super(RUN);
+ * this.greetee = greetee;
+ * }
+ * // the entry point function is computed once:
+ * private static final MethodHandle RUN
+ * = MethodHandles.findVirtual(MyMethodHandle.class, "run",
+ * MethodType.make(void.class));
+ * }
+ * Greeter greeter = new Greeter("world");
+ * greeter.run(); // prints "hello, world"
+ * MethodHandle mh = greeter;
+ * mh.invoke(); // also prints "hello, world"
+ * </pre></blockquote>
+ * <p>
+ * In this example, the method {@code run} provides the entry point.
+ * The entry point need not be a constant value; it may be independently
+ * computed in each call to the constructor. The entry point does not
+ * even need to be a method on the Java method handle class, though
+ * that is the typical case.

+/**
+ * A method handle is a typed reference to the entry point of a method.
+ * <p>
+ * Method handles are strongly typed according to signature.
+ * They are not distinguished by method name or enclosing class.
+ * A method handle must be invoked under a signature which exactly matches
+ * the method handle's own type.
+ * <p>
+ * Every method handle confesses its type via the <code>type</code> accessor.
+ * The structure of this type is a series of classes, one of which is
+ * the return type of the method (or <code>void.class</code> if none).
+ * <p>
+ * Every method handle appears as an object containing a method named
+ * <code>invoke</code>, whose signature exactly matches
+ * the method handle's type.
+ * A normal Java method call (using the <code>invokevirtual</code> instruction)
+ * can invoke this method from Java source code (if language support is present).
+ * <p>
+ * Every call to a method handle specifies an intended method type,
+ * which must exactly match the type of the method handle.
+ * (The type is specified in the <code>invokevirtual</code> instruction,
+ * via a {@code CONSTANT_NameAndType} constant pool entry.)
+ * The call looks within the receiver object for a method
+ * named <code>invoke</code> of the intended method type.
+ * The call fails with a {@link WrongMethodTypeException}
+ * if the method does not exist, even if there is an <code>invoke</code>
+ * method of a closely similar signature.
+ * <p>
+ * A method handle is an unrestricted capability to call a method.
+ * A method handle can be formed on a non-public method by a class
+ * that has access to that method; the resulting handle can be used
+ * in any place by any caller who receives a reference to it. Thus, access
+ * checking is performed when the method handle is created, not
+ * (as in reflection) every time it is called. Handles to non-public
+ * methods, or in non-public classes, should generally be kept secret.
+ * They should not be passed to untrusted code.
+ * <p>
+ * Bytecode in an extended JVM can directly call a method handle's
+ * <code>invoke</code> from an <code>invokevirtual</code> instruction.
+ * The receiver class type must be <code>MethodHandle</code> and the method name
+ * must be <code>invoke</code>. The signature of the invocation
+ * (after resolving symbolic type names) must exactly match the method type
+ * of the target method.
+ * <p>
+ * Bytecode in an extended JVM can directly obtain a method handle
+ * for any accessible method from a <code>ldc</code> instruction
+ * which refers to a <code>CONSTANT_Methodref</code> or
+ * <code>CONSTANT_InterfaceMethodref</code> constant pool entry.
+ * <p>
+ * All JVMs can also use a reflective API called <code>MethodHandles</code>
+ * for creating and calling method handles.
+ * <p>
+ * A method reference may refer either to a static or non-static method.
+ * In the non-static case, the method handle type includes an explicit
+ * receiver argument, prepended before any other arguments.
+ * In the method handle's type, the initial receiver argument is typed
+ * according to the class under which the method was initially requested.
+ * (E.g., if a non-static method handle is obtained via <code>ldc</code>,
+ * the type of the receiver is the class named in the constant pool entry.)
+ * <p>
+ * When a method handle to a virtual method is invoked, the method is
+ * always looked up in the receiver (that is, the first argument).
+ * <p>
+ * A non-virtual method handles to a specific virtual method implementation
+ * can also be created. These do not perform virtual lookup based on
+ * receiver type. Such a method handle simulates the effect of
+ * an <code>invokespecial</code> instruction to the same method.

+ * A factory object for creating method handles, when the creation

+ * access checks when they are called; this is a major difference
+ * from reflective {@link Method}, which performs access checking
+ * against every caller, on every call. Method handle access
+ * restrictions are enforced when a method handle is created.
+ * The caller class against which those restrictions are enforced
+ * is known as the "lookup class". {@link Lookup} embodies an
+ * authenticated lookup class, and can be used to create any number
+ * of access-checked method handles, all checked against a single
+ * lookup class.
+ * <p>
+ * A class which needs to create method handles will call
+ * {@code MethodHandles.lookup()} to create a factory for itself.
+ * It may then use this factory to create method handles on
+ * all of its methods, including private ones.
+ * It may also delegate the lookup (e.g., to a metaobject protocol)
+ * by passing the {@code Lookup} object to other code.
+ * If this other code creates method handles, they will be access
+ * checked against the original lookup class, and not with any higher
+ * privileges.
+ * <p>
+ * Note that access checks only apply to named and reflected methods.
+ * Other method handle creation methods, such as {@link #convertArguments},
+ * do not require any access checks, and can be done independently
+ * of any lookup class.
+ * <p>
+ * <em>A note about error conditions:<em> A lookup can fail, because
+ * the containing class is not accessible to the lookup class, or
+ * because the desired class member is missing, or because the
+ * desired class member is not accessible to the lookup class.
+ * It can also fail if a security manager is installed and refuses
+ * access. In any of these cases, an exception will be
+ * thrown from the attempted lookup.
+ * In general, the conditions under which a method handle may be
+ * created for a method M are exactly as restrictive as the conditions
+ * under which the lookup class could have compiled a call to M.

+ * (The types do not need to be related in any particular way.
+ * The treatment of interfaces follows the usage of the bytecode verifier.)
+ * <li>If T0 and T1 are primitives, then a Java casting
+ * conversion (JLS 5.5) is applied, if one exists.
+ * <li>If T0 and T1 are primitives and one is boolean,
+ * the boolean is treated as a one-bit unsigned integer.
+ * (This treatment follows the usage of the bytecode verifier.)
+ * A conversion from another primitive type behaves as if
+ * it first converts to byte, and then masks all but the low bit.
+ * <li>If T0 is a primitive and T1 a reference, a boxing
+ * conversion is applied if one exists, possibly followed by
+ * an reference conversion to a superclass.
+ * T1 must be a wrapper class or a supertype of one.
+ * If T1 is a wrapper class, T0 is converted if necessary
+ * to T1's primitive type by one of the preceding conversions.

+ * T0 must be a wrapper class or a supertype of one.

+ * Anonymous class loader. Will load any valid classfile, producing
+ * a {@link Class} metaobject, without installing that class in the
+ * system dictionary. Therefore, {@link Class#forName(String)} will never
+ * produce a reference to an anonymous class.
+ * <p>
+ * The access permissions of the anonymous class are borrowed from
+ * a <em>host class</em>. The new class behaves as if it were an
+ * inner class of the host class. It can access the host's private
+ * members, if the creator of the class loader has permission to
+ * do so (or to create accessible reflective objects).
+ * <p>
+ * When the anonymous class is loaded, elements of its constant pool
+ * can be patched to new values. This provides a hook to pre-resolve
+ * named classes in the constant pool to other classes, including
+ * anonymous ones. Also, string constants can be pre-resolved to
+ * any reference. (The verifier treats non-string, non-class reference
+ * constants as plain objects.)
+ * <p>
+ * Why include the patching function? It makes some use cases much easier.
+ * Second, the constant pool needed some internal patching anyway,
+ * to anonymize the loaded class itself. Finally, if you are going
+ * to use this seriously, you'll want to build anonymous classes
+ * on top of pre-existing anonymous classes, and that requires patching.
+ *
+ * <p>%%% TO-DO:
+ * <ul>
+ * <li>needs better documentation</li>
+ * <li>needs more security work (for safe delegation)</li>
+ * <li>needs a clearer story about error processing</li>
+ * <li>patch member references also (use ';' as delimiter char)</li>
+ * <li>patch method references to (conforming) method handles</li>
+ * </ul>

+/**
+ * Utility routines for dealing with bytecode-level names.
+ * Includes universal mangling rules for the JVM.
+ *
+ * <h3>Avoiding Dangerous Characters </h3>
+ *
+ * <p>
+ * The JVM defines a very small set of characters which are illegal
+ * in name spellings. We will slightly extend and regularize this set
+ * into a group of <cite>dangerous characters</cite>.
+ * These characters will then be replaced, in mangled names, by escape sequences.
+ * In addition, accidental escape sequences must be further escaped.
+ * Finally, a special prefix will be applied if and only if
+ * the mangling would otherwise fail to begin with the escape character.
+ * This happens to cover the corner case of the null string,
+ * and also clearly marks symbols which need demangling.
+ * </p>
+ * <p>
+ * Dangerous characters are the union of all characters forbidden
+ * or otherwise restricted by the JVM specification,
+ * plus their mates, if they are brackets
+ * (<code><big><b>[</b></big></code> and <code><big><b>]</b></big></code>,
+ * <code><big><b><</b></big></code> and <code><big><b>></b></big></code>),
+ * plus, arbitrarily, the colon character <code><big><b>:</b></big></code>.
+ * There is no distinction between type, method, and field names.
+ * This makes it easier to convert between mangled names of different
+ * types, since they do not need to be decoded (demangled).
+ * </p>
+ * <p>
+ * The escape character is backslash <code><big><b>\</b></big></code>
+ * (also known as reverse solidus).
+ * This character is, until now, unheard of in bytecode names,
+ * but traditional in the proposed role.
+ *
+ * </p>
+ * <h3> Replacement Characters </h3>
+ *
+ *
+ * <p>
+ * Every escape sequence is two characters
+ * (in fact, two UTF8 bytes) beginning with
+ * the escape character and followed by a
+ * <cite>replacement character</cite>.
+ * (Since the replacement character is never a backslash,
+ * iterated manglings do not double in size.)
+ * </p>
+ * <p>
+ * Each dangerous character has some rough visual similarity
+ * to its corresponding replacement character.
+ * This makes mangled symbols easier to recognize by sight.
+ * </p>
+ * <p>
+ * The dangerous characters are
+ * <code><big><b>/</b></big></code> (forward slash, used to delimit package components),
+ * <code><big><b>.</b></big></code> (dot, also a package delimiter),
+ * <code><big><b>;</b></big></code> (semicolon, used in signatures),
+ * <code><big><b>$</b></big></code> (dollar, used in inner classes and synthetic members),
+ * <code><big><b><</b></big></code> (left angle),
+ * <code><big><b>></b></big></code> (right angle),
+ * <code><big><b>[</b></big></code> (left square bracket, used in array types),
+ * <code><big><b>]</b></big></code> (right square bracket, reserved in this scheme for language use),
+ * and <code><big><b>:</b></big></code> (colon, reserved in this scheme for language use).
+ * Their replacements are, respectively,
+ * <code><big><b>|</b></big></code> (vertical bar),
+ * <code><big><b>,</b></big></code> (comma),
+ * <code><big><b>?</b></big></code> (question mark),
+ * <code><big><b>%</b></big></code> (percent),
+ * <code><big><b>^</b></big></code> (caret),
+ * <code><big><b>_</b></big></code> (underscore), and
+ * <code><big><b>{</b></big></code> (left curly bracket),
+ * <code><big><b>}</b></big></code> (right curly bracket),
+ * <code><big><b>!</b></big></code> (exclamation mark).
+ * In addition, the replacement character for the escape character itself is
+ * <code><big><b>-</b></big></code> (hyphen),
+ * and the replacement character for the null prefix is
+ * <code><big><b>=</b></big></code> (equal sign).
+ * </p>
+ * <p>
+ * An escape character <code><big><b>\</b></big></code>
+ * followed by any of these replacement characters
+ * is an escape sequence, and there are no other escape sequences.
+ * An equal sign is only part of an escape sequence
+ * if it is the second character in the whole string, following a backslash.
+ * Two consecutive backslashes do <em>not</em> form an escape sequence.
+ * </p>
+ * <p>
+ * Each escape sequence replaces a so-called <cite>original character</cite>
+ * which is either one of the dangerous characters or the escape character.
+ * A null prefix replaces an initial null string, not a character.
+ * </p>
+ * <p>
+ * All this implies that escape sequences cannot overlap and may be
+ * determined all at once for a whole string. Note that a spelling
+ * string can contain <cite>accidental escapes</cite>, apparent escape
+ * sequences which must not be interpreted as manglings.
+ * These are disabled by replacing their leading backslash with an
+ * escape sequence (<code><big><b>\-</b></big></code>). To mangle a string, three logical steps
+ * are required, though they may be carried out in one pass:
+ * </p>
+ * <ol>
+ * <li>In each accidental escape, replace the backslash with an escape sequence
+ * (<code><big><b>\-</b></big></code>).</li>
+ * <li>Replace each dangerous character with an escape sequence
+ * (<code><big><b>\|</b></big></code> for <code><big><b>/</b></big></code>, etc.).</li>
+ * <li>If the first two steps introduced any change, <em>and</em>
+ * if the string does not already begin with a backslash, prepend a null prefix (<code><big><b>\=</b></big></code>).</li>
+ * </ol>
+ *
+ * To demangle a mangled string that begins with an escape,
+ * remove any null prefix, and then replace (in parallel)
+ * each escape sequence by its original character.
+ * <p>Spelling strings which contain accidental
+ * escapes <em>must</em> have them replaced, even if those
+ * strings do not contain dangerous characters.
+ * This restriction means that mangling a string always
+ * requires a scan of the string for escapes.
+ * But then, a scan would be required anyway,
+ * to check for dangerous characters.
+ *
+ * </p>
+ * <h3> Nice Properties </h3>
+ *
+ * <p>
+ * If a bytecode name does not contain any escape sequence,
+ * demangling is a no-op: The string demangles to itself.
+ * Such a string is called <cite>self-mangling</cite>.
+ * Almost all strings are self-mangling.
+ * In practice, to demangle almost any name “found in nature”,
+ * simply verify that it does not begin with a backslash.
+ * </p>
+ * <p>
+ * Mangling is a one-to-one function, while demangling
+ * is a many-to-one function.
+ * A mangled string is defined as <cite>validly mangled</cite> if
+ * it is in fact the unique mangling of its spelling string.
+ * Three examples of invalidly mangled strings are <code><big><b>\=foo</b></big></code>,
+ * <code><big><b>\-bar</b></big></code>, and <code><big><b>baz\!</b></big></code>, which demangle to <code><big><b>foo</b></big></code>, <code><big><b>\bar</b></big></code>, and
+ * <code><big><b>baz\!</b></big></code>, but then remangle to <code><big><b>foo</b></big></code>, <code><big><b>\bar</b></big></code>, and <code><big><b>\=baz\-!</b></big></code>.
+ * If a language back-end or runtime is using mangled names,
+ * it should never present an invalidly mangled bytecode
+ * name to the JVM. If the runtime encounters one,
+ * it should also report an error, since such an occurrence
+ * probably indicates a bug in name encoding which
+ * will lead to errors in linkage.
+ * However, this note does not propose that the JVM verifier
+ * detect invalidly mangled names.
+ * </p>
+ * <p>
+ * As a result of these rules, it is a simple matter to
+ * compute validly mangled substrings and concatenations
+ * of validly mangled strings, and (with a little care)
+ * these correspond to corresponding operations on their
+ * spelling strings.
+ * </p>
+ * <ul>
+ * <li>Any prefix of a validly mangled string is also validly mangled,
+ * although a null prefix may need to be removed.</li>
+ * <li>Any suffix of a validly mangled string is also validly mangled,
+ * although a null prefix may need to be added.</li>
+ * <li>Two validly mangled strings, when concatenated,
+ * are also validly mangled, although any null prefix
+ * must be removed from the second string,
+ * and a trailing backslash on the first string may need escaping,
+ * if it would participate in an accidental escape when followed
+ * by the first character of the second string.</li>
+ * </ul>
+ * <p>If languages that include non-Java symbol spellings use this
+ * mangling convention, they will enjoy the following advantages:
+ * </p>
+ * <ul>
+ * <li>They can interoperate via symbols they share in common.</li>
+ * <li>Low-level tools, such as backtrace printers, will have readable displays.</li>
+ * <li>Future JVM and language extensions can safely use the dangerous characters
+ * for structuring symbols, but will never interfere with valid spellings.</li>
+ * <li>Runtimes and compilers can use standard libraries for mangling and demangling.</li>
+ * <li>Occasional transliterations and name composition will be simple and regular,
+ * for classes, methods, and fields.</li>
+ * <li>Bytecode names will continue to be compact.
+ * When mangled, spellings will at most double in length, either in
+ * UTF8 or UTF16 format, and most will not change at all.</li>
+ * </ul>
+ *
+ *
+ * <h3> Suggestions for Human Readable Presentations </h3>
+ *
+ *
+ * <p>
+ * For human readable displays of symbols,
+ * it will be better to present a string-like quoted
+ * representation of the spelling, because JVM users
+ * are generally familiar with such tokens.
+ * We suggest using single or double quotes before and after
+ * mangled symbols which are not valid Java identifiers,
+ * with quotes, backslashes, and non-printing characters
+ * escaped as if for literals in the Java language.
+ * </p>
+ * <p>
+ * For example, an HTML-like spelling
+ * <code><big><b><pre></b></big></code> mangles to
+ * <code><big><b>\^pre\_</b></big></code> and could
+ * display more cleanly as
+ * <code><big><b>'<pre>'</b></big></code>,
+ * with the quotes included.
+ * Such string-like conventions are <em>not</em> suitable
+ * for mangled bytecode names, in part because
+ * dangerous characters must be eliminated, rather
+ * than just quoted. Otherwise internally structured
+ * strings like package prefixes and method signatures
+ * could not be reliably parsed.
+ * </p>
+ * <p>
+ * In such human-readable displays, invalidly mangled
+ * names should <em>not</em> be demangled and quoted,
+ * for this would be misleading. Likewise, JVM symbols
+ * which contain dangerous characters (like dots in field
+ * names or brackets in method names) should not be
+ * simply quoted. The bytecode names
+ * <code><big><b>\=phase\,1</b></big></code> and
+ * <code><big><b>phase.1</b></big></code> are distinct,
+ * and in demangled displays they should be presented as
+ * <code><big><b>'phase.1'</b></big></code> and something like
+ * <code><big><b>'phase'.1</b></big></code>, respectively.
+ * </p>
