SPECjvm2008/xml.transform with CDS fails with "can't seal package nu.xom"

Run SPECjvm2008 with the following parameters

java \
    --add-exports=java.xml/com.sun.org.apache.xerces.internal.parsers=ALL-UNNAMED \
    --add-exports=java.xml/com.sun.org.apache.xerces.internal.util=ALL-UNNAMED \
    -Xms3g -Xmx3g -Xlog:gc \
    -jar SPECjvm2008/SPECjvm2008.jar xml.transform \
    -ikv -fit 1 -wt 0 -i 1 -bt 1

If we change the above command to dump the classlist, create a CDS archive, and run with the CDS archive, the following exception is displayed:
=====
  Benchmark: xml.transform
  Run mode: timed run
  Test type: multi
  Threads: 1
  Iterations: 40
  Run length: 1s
xom canonicalization of chess-fo/Kasparov-Karpov.xml.SAX crashed.
===

If we change the classlist to have only a single line with the class "nu.xom.Node", dump the archive and run the app again, the following exception stack is printed:
