I did think they used to work at Java 6 (Apple's jdk build)
I thought I used to get some jit stats dumped at application shutdown, by including some option or other.
That doesn't appear to be working with the openjdk 7 build.
I tried various other options with command line launched code, including gc ones, and saw no output, I didn't see the invalid option error you indicated either.
I have for now decided to cut over to using the jstat command runtime exec'ed for the JIT info. Actually, better suited to how I've been handling similar from my application  anyhow.
Some other time maybe I'll try to figure out why I am seeing nothing on the other HotSpot options.

Thanks for the detailed response.
