After upgrading Bamboo get WARNings server at bitbucket presented unverified rsa key

[Scott Strmel]

Upgraded Bamboo from 5.9.7 to 5.12.2 and now logging warnings "server at Bitbucket presented unverified RSA key". Bitbucket server (4.2.0) has "SSH enabled", "SSH access keys enabled", and SSH port=7999. Access keys exist on each repository. Nothing has changed on the Bitbucket side.

It's part of Trusted keys management feature, you can ignore this warning if you don't want to enable Trusted keys management.
