Since JDK-8317269, when assembling an AOT cache, AOT class linking can be disabled under a few circumstances:

1. -XX:-AOTClassLinking is specified
2. -XX:-UseCompressedClassPointers (this disabled heap dumping)
3. Fill module graph caching is disabled due to incompatible module flags

In an old class is loaded by the application during the training run, we could get an assert like this:

#  assert(can_be_verified_at_dumptime()) failed: must be
