EVALUATION There is a window during the allocation of a constant pool cache during a rewrite() in which the return of size() of a constant pool cache oop is not the final size and is inconsistent with the allocation done for that constant pool cache oop. This inconsistency is the source of the assertion failure regarding the P-bits. This inconsistency is visible during CMS concurrent precleaning.
