>> ClassLoaderExt::check() was only called for the boot loader. This function was needed to handle app classes when the boot loader was used to load all boot/platform/app classes at CDS dump time. Starting from JDK 10, platform&  app classes are no longer loaded by the boot loader at dump time. So ClassLoaderExt::check() is no longer needed and should be removed.
