Could you please provide .jtr files along with the jtreg test results?

Hi Rory,

thanks for the confirmation. Vladimir just confirmed this as well on
the hotspot list.
The RTM feature is not on by default so this problem is not as sever
as I initially thought.

The unfortunate thing is that these tests are showing up "Passed"
instead of "Not executed". I think this is not easy to fix in jtreg
because the tests are actually executed and only at runtime the test
decides that its pay load can't be executed on the actual hardware.

Maybe we need some special return codes such that tests can express
that a tests wasn't really executed. However that would probably
require the redesign of many test because many of them execute several
subtests depending on the platform. But I think it would be definitely
valuable if the jtreg results would be more accurate.
