Correct Compiler for ARM / Arch64 for the jdk8u forest? (-m64 not supported)

Thu Apr 20 12:21:39 UTC 2017

Hi Erik/Andrew/Dalibor,

Ah that clears it up - we were getting confused with what port was in
mainstream or not.  OK, we'll pick the ssh://hg.openjdk.java.net/
aarch64-port/jdk8u for our Java 8 build (Zero is interesting, but of less
use to the wider community) and then we'll see what happens for 9 and 10 a
little down the line.

Thanks all again for the speedy assistance!

Cheers,
Martijn
