        Description

        OopStorage introduced a bespoke RCU-inspired mechanism in the management of its arrays of blocks (part of JDK-8200557). This mechanism was developed before GlobalCounter (JDK-8195099) was available, and has continued to be used due to a limitation of GlobalCounter (it could attempt to safepoint, due to JDK-8191798). Now that the limitation has been addressed, OopStorage should use GlobalCounter and discard its private mechanism.
