Great, thanks!

Yep, you need a second reviewer for these patches.

The tests should be run in order to verify your changes. Since your
changes make Linux/sparc64 work again, they should be run on Linux/sparc64.

Ok, this is the part I don't really understand yet. Why run with Zero on
Linux/sparc64? Shouldn't it be possible to run HotSpot "natively" (with
the template interpreter, C1, C2) on Linux/sparc64?

Thanks,
