We had tried moving to Alpine 3.5 when it came out, but reverted it with #92 since it could be a breaking change for many users. That said, since this is the simplest way to get the Java 8 update via Alpine packages, I think we might be ok to bump the Alpine version since this will also be a bump on the Java version.

While I don't like breaking people but I am guessing the CVE's mentioned in the Oracle patch advisory are more important and the users have a specific version jump to test the updated Alpine version.

If this is accepted, could you also update the update.sh script to ensure the right Alpine version when run by the bot?

@yosifkit done, I have created new pull request with updated update.sh script.
