Patch does not apply cleanly due to different context, before [JDK-8250825](https://bugs.openjdk.org/browse/JDK-8250825)  the  PR [JDK-8230505](https://bugs.openjdk.org/browse/JDK-8230505) change releated lines, and I think [JDK-8230505](https://bugs.openjdk.org/browse/JDK-8230505) do not needed backport to jdk8u-dev.
