Lgtm, nice catch!

One nit: the name of the bug does not indicate what "missing klass" means, I would prefer spelling it out like:

Parallel: Missing iteration over klass when marking objArrays/objArrayOops during Full GC

or

Parallel does not mark/iterate over/process klass for objArrays/objArrayOops during Full GC
