RFR: 8263538: SharedArchiveConsistency.java should test -Xshare:auto as well

[Yumin Qi]

Hi, please review

  When this test run with -Xshare:on, it will exit when the shared archive is corrupted or mismatch. Make it run with -Xshare:auto will expand code coverage and to keep app run without using the CDS.

  Tests: Mach5 tier1,tier4

Thanks
Yumin
