The fix for JDK-8055006 was reviewed by several engineers and was pushed
directly to 8u40 due to time constraints. This is a forward port to get the same
changes into JDK 9.
There are two webrevs, one for HotSpot and one for the JDK.
The 8u40 HotSpot change applied cleanly to 9 so if this was a traditional
backport it wouldn't require another review. But since this is a weird situation
and I'm pushing to 9 I'll ask for reviews just to be on the safe side.
Also, the original 8u40 push contained some unnecessary changes that was later
cleaned up by JDK-8056056. In this port to 9 I have merged these two changes
into one to avoid introducing a known issue only to remove it again.
The JDK change is new. The makefiles differ between 8u40 and 9 and this new
change makes use of functionality not present in 8u40. This patch was provided
by Erik Joelsson and I have reviewed it myself, but it needs two reviews so
another one is welcome.
