We have seen this happening intermittently when running some tests in JMH with -XX:ArchiveClassesAtExit=dynamic.jsa.

MetaspaceShared::try_link_class() encounters an old class that's already in the static archive. It calls set_class_has_failed_verification() on it, but the SystemDictionaryShared doesn't have a DumpTimeClassInfo that were loading from the static archive:

Stack: [0x00007f124479b000,0x00007f124489c000], sp=0x00007f124489a5b0, free space=1021k

Thus, "p" is null in the following code:

void SystemDictionaryShared::set_class_has_failed_verification(InstanceKlass* ik) {
  Arguments::assert_is_dumping_archive();
  DumpTimeClassInfo* p = get_info(ik);
  p->set_failed_verification();
 }
