The test case deletes `baseArchiveName` and then try to use the `-XX:+AutoCreateSharedArchive` flag, etc, to trigger a dynamic dump, which usually will fail (because the base archive doesn't exist) and print out the expected warning.

However, when `-vmoption:-Xshare:off` is specified, `isUseSharedSpacesDisabled()` returns true, and the `run`  method will internally recreated a base archive. This behavior is intended to make all the tests in the `dynamicArchive/` subdirectory work even if `-Xshare:off` is specified, but this would cause the two newly added test cases to fail.
