Hi Ogata, you need to backport JDK-8185975 before you can use +8 instead of -8. Please don't forget to test the debug build.

Since not a small number of customers are still using jdk8, especially in AIX, JDK-8188868 is important for them to improve performance of secure network transportation. Regards, Ogata
