+// - data: bytes of a class file, a raw memory address (length gives the number of bytes)
+// - cp_patches: where non-null entries exist, they replace corresponding CP entries in data
+
+// When you load an anonymous class U, it works as if you changed its name just before loading,
+// to a name that you will never use again. Since the name is lost, no other class can directly
+// link to any member of U. Just after U is loaded, the only way to use it is reflectively,
+// through java.lang.Class methods like Class.newInstance.
+
+// Access checks for linkage sites within U continue to follow the same rules as for named classes.
+// The package of an anonymous class is given by the package qualifier on the name under which it was loaded.
+// An anonymous class also has special privileges to access any member of its host class.
+// This is the main reason why this loading operation is unsafe. The purpose of this is to
+// allow language implementations to simulate "open classes"; a host class in effect gets
+// new code when an anonymous class is loaded alongside it. A less convenient but more
+// standard way to do this is with reflection, which can also be set to ignore access
+// restrictions.
+
+// Access into an anonymous class is possible only through reflection. Therefore, there
+// are no special access rules for calling into an anonymous class. The relaxed access
+// rule for the host class is applied in the opposite direction: A host class reflectively
+// access one of its anonymous classes.
+
+// If you load the same bytecodes twice, you get two different classes. You can reload
+// the same bytecodes with or without varying CP patches.
+
+// By using the CP patching array, you can have a new anonymous class U2 refer to an older one U1.
+// The bytecodes for U2 should refer to U1 by a symbolic name (doesn't matter what the name is).
+// The CONSTANT_Class entry for that name can be patched to refer directly to U1.
+
+// This allows, for example, U2 to use U1 as a superclass or super-interface, or as
+// an outer class (so that U2 is an anonymous inner class of anonymous U1).
+// It is not possible for a named class, or an older anonymous class, to refer by
+// name (via its CP) to a newer anonymous class.
+
+// CP patching may also be used to modify (i.e., hack) the names of methods, classes,
+// or type descriptors used in the loaded anonymous class.
+
+// Finally, CP patching may be used to introduce "live" objects into the constant pool,
+// instead of "dead" strings. A compiled statement like println((Object)"hello") can
+// be changed to println(greeting), where greeting is an arbitrary object created before
+// the anonymous class is loaded. This is useful in dynamic languages, in which
+// various kinds of metaobjects must be introduced as constants into bytecode.
+// Note the cast (Object), which tells the verifier to expect an arbitrary object,
+// not just a literal string. For such ldc instructions, the verifier uses the
+// type Object instead of String, if the loaded constant is not in fact a String.
