        Description

        In ConcurrentMark::weakRefsWork(), if the mark stack overflows we should not proceed to prune the string and symbol tables because we can't trust the g1_is_alive closure until marking has completed.

        Before starting to unlink elements from the string and symbol table we should check that has_overflown() is false.
