- * A {@code CallSite} reifies an {@code invokedynamic} instruction from bytecode,

- * Every linked {@code CallSite} object corresponds to a distinct instance
- * of the {@code invokedynamic} instruction, and vice versa.
+ * A {@code CallSite} is a holder for a variable {@link MethodHandle},
+ * which is called its {@code target}.
+ * Every call to a {@code CallSite} is delegated to the site's current target.
  * <p>
- * Every linked {@code CallSite} object has one state variable,
- * a {@link MethodHandle} reference called the {@code target}.
- * This reference is never null.  Though it can change its value
- * successive values must always have exactly the {@link MethodType method type}
- * called for by the bytecodes of the associated {@code invokedynamic} instruction
+ * A call site is initially created in an <em>unlinked</em> state,
+ * which is distinguished by a null target variable.
+ * Before the call site may be invoked (and before certain other
+ * operations are attempted), the call site must be linked to
+ * a non-null target.
  * <p>
- * It is the responsibility of each class's
- * {@link Linkage#registerBootstrapMethod(Class, MethodHandle) bootstrap method}
- * to produce call sites which have been pre-linked to an initial target method.
- * The required {@link MethodType type} for the target method is a parameter
- * to each bootstrap method call.
- * <p>
- * The bootstrap method may elect to produce call sites of a
- * language-specific subclass of {@code CallSite}.  In such a case,
- * the subclass may claim responsibility for initializing its target to
- * a non-null value, by overriding {@link #initialTarget}.
- * <p>
- * An {@code invokedynamic} instruction which has not yet been executed
- * is said to be <em>unlinked</em>.  When an unlinked call site is executed,
- * the containing class's bootstrap method is called to manufacture a call site,
- * for the instruction.  If the bootstrap method does not assign a non-null
- * value to the new call site's target variable, the method {@link #initialTarget}
- * is called to produce the new call site's first target method.
- * <p>
- * A freshly-created {@code CallSite} object is not yet in a linked state.
- * An unlinked {@code CallSite} object reports null for its {@code callerClass}.
- * When the JVM receives a {@code CallSite} object from a bootstrap method,
- * it first ensures that its target is non-null and of the correct type.
- * The JVM then links the {@code CallSite} object to the call site instruction,
- * enabling the {@code callerClass} to return the class in which the instruction occurs.
- * <p>
- * Next, the JVM links the instruction to the {@code CallSite}, at which point
- * any further execution of the {@code invokedynamic} instruction implicitly
- * invokes the current target of the {@code CallSite} object.
- * After this two-way linkage, both the instruction and the {@code CallSite}
- * object are said to be linked.
- * <p>
- * This state of linkage continues until the method containing the
- * dynamic call site is garbage collected, or the dynamic call site
- * is invalidated by an explicit request.
+ * A call site may be <em>relinked</em> by changing its target.
+ * The new target must be non-null and must have the same
+ * {@linkplain MethodHandle#type() type}
+ * as the previous target.
+ * Thus, though a call site can be relinked to a series of
+ * successive targets, it cannot change its type.

  *
+ * <h2><a name="bsm"></a>Bootstrap Methods</h2>
+ * Before the JVM can execute a dynamic call site (an {@code invokedynamic} instruction),
+ * the call site must first be <em>linked</em>.
+ * Linking is accomplished by calling a <em>bootstrap method</em>
+ * which is given the static information content of the call site,
+ * and which must produce a {@link java.dyn.MethodHandle method handle}
+ * that gives the behavior of the call site.
+ * <p>
+ * Each {@code invokedynamic} instruction statically specifies its own
+ * bootstrap method as a constant pool reference.
+ * The constant pool reference also specifies the call site's name and type signature,
+ * just like {@code invokevirtual} and the other invoke instructions.
+ * <p>
+ * Linking starts with resolving the constant pool entry for the
+ * bootstrap method, and resolving a {@link java.dyn.MethodType MethodType} object for
+ * the type signature of the dynamic call site.
+ * This resolution process may trigger class loading.
+ * It may therefore throw an error if a class fails to load.
+ * This error becomes the abnormal termination of the dynamic
+ * call site execution.
+ * Linkage does not trigger class initialization.
+ * <p>
+ * Next, the bootstrap method call is started, with four values being stacked:
+ * <ul>
+ * <li>a {@code MethodHandle}, the resolved bootstrap method itself </li>
+ * <li>a {@code Class}, the <em>caller class</em> in which dynamic call site occurs </li>
+ * <li>a {@code String}, the method name mentioned in the call site </li>
+ * <li>a {@code MethodType}, the resolved type signature of the call </li>
+ * </ul>
+ * The method handle is then applied to the other values as if by
+ * {@linkplain java.dyn.MethodHandle#invokeGeneric the <code>invokeGeneric</code> method}.
+ * The returned result must be a {@link java.dyn.CallSite CallSite}, a {@link java.dyn.MethodHandle MethodHandle},
+ * or another {@link java.dyn.MethodHandleProvider MethodHandleProvider} value.
+ * The method {@linkplain java.dyn.MethodHandleProvider#asMethodHandle asMethodHandle}
+ * is then called on the returned value.  The result of that second
+ * call is the {@code MethodHandle} which becomes the
+ * permanent binding for the dynamic call site.
+ * That method handle's type must be exactly equal to the type
+ * derived from the dynamic call site signature and passed to
+ * the bootstrap method.
+ * <p>
+ * After resolution, the linkage process may fail in a variety of ways.
+ * All failures are reported by an {@link java.dyn.InvokeDynamicBootstrapError InvokeDynamicBootstrapError},
+ * which is thrown as the abnormal termination of the dynamic call
+ * site execution.
+ * The following circumstances will cause this:
+ * <ul>
+ * <li>the bootstrap method invocation completes abnormally </li>
+ * <li>the result from the bootstrap invocation is not a reference to
+ *     an object of type {@link java.dyn.MethodHandleProvider MethodHandleProvider} </li>
+ * <li>the call to {@code asMethodHandle} completes abnormally </li>
+ * <li>the call to {@code asMethodHandle} fails to return a reference to
+ *     an object of type {@link java.dyn.MethodHandle MethodHandle} </li>
+ * <li>the method handle produced by {@code asMethodHandle} does not have
+ *     the expected {@code MethodType} </li>
+ * </ul>
+ * <h3>timing of linkage</h3>
+ * A dynamic call site is linked just before its first execution.
+ * The bootstrap method call implementing the linkage occurs within
+ * a thread that is attempting a first execution.
+ * <p>
+ * If there are several such threads, the JVM picks one thread
+ * and runs the bootstrap method while the others wait for the
+ * invocation to terminate normally or abnormally.
+ * <p>
+ * After a bootstrap method is called and a method handle target
+ * successfully extracted, the JVM attempts to link the instruction
+ * being executed to the target method handle.
+ * This may fail if there has been intervening linkage
+ * or invalidation event for the same instruction.
+ * If such a failure occurs, the dynamic call site must be
+ * re-executed from the beginning, either re-linking it
+ * (if it has been invalidated) or invoking the target
+ * (if it the instruction has been linked by some other means).
+ * <p>
+ * If the instruction is linked successfully, the target method
+ * handle is invoked to complete the instruction execution.
+ * The state of linkage continues until the method containing the
+ * dynamic call site is garbage collected, or the dynamic call site
+ * is invalidated by an explicit request,
+ * such as {@link java.dyn.Linkage#invalidateCallerClass Linkage.invalidateCallerClass}.
+ * <p>
+ * In an application which requires dynamic call sites with individually
+ * mutable behaviors, their bootstrap methods should produce distinct
+ * {@link java.dyn.CallSite CallSite} objects, one for each linkage request.
+ * <p>
+ * If a class containing {@code invokedynamic} instructions
+ * is {@linkplain java.dyn.Linkage#invalidateCallerClass(Class) invalidated},
+ * subsequent execution of those {@code invokedynamic} instructions
+ * will require linking.
+ * It is as if they had never been executed in the first place.
+ * (However, invalidation does not cause constant pool entries to be
+ * resolved a second time.)
+ * <p>
+ * Invalidation events and bootstrap method calls for a particular
+ * dynamic call site are globally ordered relative to each other.
+ * When an invokedynamic instruction is invalidated, if there is
+ * simultaneously a bootstrap method invocation in process
+ * (in the same thread or a different thread), the result
+ * eventually returned must not be used to link the call site.
+ * Put another way, when a call site is invalidated, its
+ * subsequent linkage (if any) must be performed by a bootstrap method
+ * call initiated after the invalidation occurred.
+ * <p>
+ * If several threads simultaneously execute a bootstrap method for a single dynamic
+ * call site, the JVM must choose one target object and installs it visibly to
+ * all threads.  Any other bootstrap method calls are allowed to complete, but their
+ * results are ignored, and their dynamic call site invocations proceed with the originally
+ * chosen target object.
+ * <p>
+ * The JVM is free to duplicate dynamic call sites.
+ * This means that, even if a class contains just one {@code invokedynamic}
+ * instruction, its bootstrap method may be executed several times,
+ * once for each duplicate.  Thus, bootstrap method code should not
+ * assume an exclusive one-to-one correspondence between particular occurrences
+ * of {@code invokedynamic} bytecodes in class files and linkage events.
+ * <p>
+ * In principle, each individual execution of an {@code invokedynamic}
+ * instruction could be deemed (by a conforming implementation) to be a separate
+ * duplicate, requiring its own execution of the bootstrap method.
+ * However, implementations are expected to perform code duplication
+ * (if at all) in order to improve performance, not make it worse.
