有人关注过ClassLoader的resolveClass的实现么?在Java代码中如下:

/**
 * Links the specified class.  This (misleadingly named) method may be
 * used by a class loader to link a class.  If the class <tt>c</tt> has
 * already been linked, then this method simply returns. Otherwise, the
 * class is linked as described in the "Execution" chapter of
 * <cite>The Java&trade; Language Specification</cite>.
 *
 * @param  c
 *         The class to link
 *
 * @throws  NullPointerException
 *          If <tt>c</tt> is <tt>null</tt>.
 *
 * @see  #defineClass(String, byte[], int, int)
 */
protected final void resolveClass(Class<?> c) {
    resolveClass0(c);
}

然后一路追到虚拟机中
https://hg.openjdk.java.net/jdk8/jdk8/hotspot/file/87ee5ee27509/src/share/vm/prims/jvm.cpp

JVM_ENTRY(void, JVM_ResolveClass(JNIEnv* env, jclass cls))
  JVMWrapper("JVM_ResolveClass");
  if (PrintJVMWarnings) warning("JVM_ResolveClass not implemented");
JVM_END

这里什么也没做啊? 而且我尝试翻了从jdk6到jdk8, 实现都是这样，这和Java代码中的"Links the specified class."是有明显出入的？有哪位大佬对于
这块比较熟悉的？还请赐教，感谢~
