The comment in the bug says this:

so I read this as you are changing Deoptimization::fetch_unroll_info to:

- fix a comment
- remove a ResetNoHandleMark

The comment in the bug doesn't mention JRT_LEAF at all, but you're
making comment changes there also.

No where in this fix do I see a ResetNoHandleMark being removed.

Is the reason for my confusion more clear yet?
