RFR: 8321474: TestAutoCreateSharedArchiveUpgrade.java should be updated with JDK 21

Thu Dec 7 18:14:16 UTC 2023

This test needs to be updated with each release since the release build number is hard coded. Now that the test has to download and install more JDKs, it will take longer to run and may timeout. A longer timeout is added as well as a minor correction where an exception was not being thrown.
