Description
The various size and index values for CMMarkStack are presently declared as being of type jint.  There is no good reason for them to be a signed type.  Better would be unsigned int or size_t.
Comments
Closing as duplicate of JDK-8160897 since that requires changes to the relevant members anyway.

Have fix. Probably going to merge it into JDK-8159422 as this is almost a rewrite.

I would vote for size_t.
