I had to add the following to the `id=aot` part of the tests:


@requires vm.cds.supports.aot.class.linking


This would exclude this part of the tests when ZGC is enabled by jtreg. Since ZGC doesn’t supported archived Java oops, all AOT method handle optimizations are disabled for ZGC. As a result, the following message will not be printed:


out.shouldMatch(".class.load. test.java.lang.invoke." + testClassName +
                "[$][$]Lambda.*/0x.*source:.*shared.*objects.*file");


So it doesn't make sense to run this part of the with ZGC.
