    Description

      Running application with option "-XX:+UseBarriersForVolatile" might have memory consistent issue like that mentioned in JDK-8241137. Since "ldar/stlr" can work well stably, we'd better simply things by removing this flag and the alternative implementation for volatile memory access.
