On my SUSE Linux x86_64 test box, with the leak (from 8308762: Metaspace leak with Instrumentation.retransform) back in the source we have this behavior

-XX:MetaspaceSize=22m -XX:MaxMetaspaceSize=22m   FAILS
-XX:MetaspaceSize=23m -XX:MaxMetaspaceSize=23m   PASSES

So I think we better go for separate settings for AIX and the rest of platforms to be on the safe side, because 23m is not really a good choice for Linux x86_64, it should still fail with the leak back in.
