Yes. The mismatch in exit code was breaking code in helios.

also, can you update the CHANGELOG file?

👍Done.

What you've changed LGTM. But I request one additional change from Integer to Long on ContainerStatus.exitCode.

[johnflavin]

I don't know that a bump all the way up to version 9.0.0 is required. 8.13.0 seems more appropriate to me.

[johnflavin]

Can you change this to "Not yet released"? The date should be set when the release is made.
