Description
Creating the archive classes_coh_valhalla.jsa with
java --enable-preview -XX:+UseCompactObjectHeaders -Xshare:dump
works with no issues, however using this archive with
java --enable-preview -Xshare:on -XX:+UseCompactObjectHeaders
leads to the following crash:

#  guarantee(prototype_header().is_inline_type()) failed: Prototype header is not inline type
