Extra JavaThread assignment in ClassLoader::create_class_path_entry()

ClassPathEntry* ClassLoader::create_class_path_entry(JavaThread* current,
                                                     const char *path, const struct stat* st,
                                                     bool is_boot_append,
                                                     bool from_class_path_attr) {
  JavaThread* thread = current->as_Java_thread();

The first arg is already a JavaThread. The "JavaThread* thread" local variable is unnecessary. Subsequent statements using "thread" could just simply use "current" instead.
