In the current JDK for LM_LEGACY and LM_LIGHTWEIGHT the `steadyStateObj` is the only Object object with a monitor when the SA agent queries.

I preferred your original fix to the test. Can you explain what the CDS issue test was? The tests shouldn't be written in such a way that makes it hard to extend functionality in LingeredApp.
