可以做一个用jdk8编译openj9的项目吗？

[MCredbear]

由于某些原因，我必须使用jdk8

Can I do a project to compile openj9 with jdk8?
For some reason I have to use jdk8

Yes, you can https://github.com/eclipse/openj9/blob/master/doc/build-instructions/Build_Instructions_V8.md.

但是它好像不能适用于arm64架构

Google translate:
But it does not seem to apply to the arm64 architecture

[JasonFengJ9]

That's correct, no ARM64 for OpenJ9 JDK8 yet.

Additional note: we have internal ARM32 build with JDK8 so some framework is there.

IBM J9 VM (build 2.9, JRE 1.8.0 Linux arm-32-Bit 20190522_417153 (JIT enabled, AOT enabled)
OpenJ9   - f73eb7f
OMR      - 2c58202
IBM      - 4972efe)
JCL - 20151231_01 based on Oracle jdk8u71-b15

so some framework is there.

in OpenJ9 itself, not in the openjdk8 extensions

[MCredbear]

那你们将来会做一个用jdk8来编译openj9的分支吗？

Google translate:
Then will you do a branch that compiles openj9 with jdk8 in the future?

[JasonFengJ9]

I think you meant OpenJ9 JDK8 aarch64, right?
As per #304 (comment), we are going to build it though no promise for the timeline.
