Plugin icons missing

I am updating a custom Confluence server plugin from v6.6.5 to v.7.1 and notice that the icons listed on Icons do not seem to be present any more (maybe since 6.7?). Are there replacements? These are not AUI icons and AUI does not have all of them so cannot be a direct replacement (eg icon-space).

Hello @K11
I believe we need to update that documentation, in the meantime please refer to our new icons definition available at Bitbucket
This was indeed done as part of Confluence 6.7
