+ * KlassFactory is an interface to implementations of the following mapping/function:
+ *
+ * Summary: create a VM internal runtime representation ("Klass")
+ from a bytestream (classfile).
+ *
+ * Input: a named bytestream in the Java class file format (see JVMS, chapter 4).
+ * Output: a VM runtime representation of a Java class
+ *
+ * Pre-conditions:
+ * a non-NULL ClassFileStream* // the classfile bytestream
+ * a non-NULL Symbol* // the name of the class
+ * a non-NULL ClassLoaderData* // the metaspace allocator
+ * (no pending exceptions)
+ *
+ * Returns:
+ * if the returned value is non-NULL, that value is an indirection (pointer/handle)
+ * to a Klass. The caller will not have a pending exception.
+ *
+ * On broken invariants and/or runtime errors the returned value will be
+ * NULL (or a NULL handle) and the caller *might* now have a pending exception.
