This only seems to have the AWTWindow.m changes:

Looking at:

https://cr.openjdk.java.net/~phh/8267545/webrev.8u.jdk.02/jdk.patch

instead, apart from the URLClassPath.c duplication, I'm concerned
about the j2secmod.h changes. Are these necessary? The j2secmod.h
in trunk is identical to that in 8u.

The addition does make sense, so it seems like it should go to trunk
first under its own bug and then be backported, unless there is a good
reason 8u should diverge here.

The rest looks fine and I see no issue with including this as a late
addition to 8u302, so the other changes for Mac OS can be utilised.
As I understand Mac OS builds were broken prior to this anyway, the
risk seems low.

Thanks,
