Description

as discussed with [e-mail] today we might want to take another look at the implementation of Node.isNodeType(String) in org.apache.jackrabbit.oak.jcr.session.NodeImpl

• avoid the explicit permission check for accessibility of jcr:mixinTypes
• only create the lazy-value for a readonly tree once (and thus only resolve it once)
• maybe load mixin types lazily and only if the primary type doesn't match

there used to be a regression in the past where deleted node mixins got revived (see OAK-7652)
