Thumbs up on this part, but I see these options mentioned in tests:

$ egrep -r 
'UseLargePagesInMetaspace|InitialBootClassLoaderMetaspaceSize' open/test 
closed/test
open/test/hotspot/jtreg/vmTestbase/metaspace/gc/MetaspaceBaseGC.java: 
useLargepages = PAGE_SIZE > 1_000_000 && 
!vmArgs.contains("-XX:-UseLargePagesInMetaspace");
open/test/hotspot/jtreg/runtime/CommandLine/OptionsValidation/TestOptionsWithRanges.java: 
excludeTestMaxRange("InitialBootClassLoaderMetaspaceSize");
open/test/hotspot/jtreg/runtime/cds/MaxMetaspaceSize.java: 
processArgs.add("-XX:InitialBootClassLoaderMetaspaceSize=1m");
open/test/hotspot/jtreg/runtime/cds/appcds/sharedStrings/LargePages.java: 
"-XX:+UseLargePages", "-XX:+UseLargePagesInMetaspace");
open/test/hotspot/jtreg/runtime/cds/appcds/sharedStrings/LargePages.java: 
"-XX:+UseLargePages", "-XX:+UseLargePagesInMetaspace");
open/test/hotspot/jtreg/runtime/Metaspace/MaxMetaspaceSizeTest.java: 
"-XX:InitialBootClassLoaderMetaspaceSize=4195328",
open/test/hotspot/jtreg/gc/TestSystemGC.java: * @run main/othervm 
-XX:+UseLargePages -XX:+UseLargePagesInMetaspace gc.TestSystemGC

Do you know of the deprecated message will affect how these tests run?
