## Symptoms
Many tests under runtime/cds/appcds/dynamicArchive are crashed when turning on VerifySharedSpaces, it reports inconsistent crc32 between dumptime and runtime(See attachments for different header content).

## How to reproduce:
$ jtreg -vmoptions:"-XX:+VerifySharedSpaces" -v:time -conc:64 -timeout:5 -jdk:/your/jdk/ test/hotspot/jtreg/runtime/cds/appcds/dynamicArchive/HelloDynamic.java
