Description
This uses the Kotlin built-in
Collections#intersectto replacecapabilities.any { allowedCapabilities.contains(it) }withcapabilities.intersect(allowedCapabilities).isNotEmpty(). To my eyes, this form is easier to grok. I wouldn't be surprised if theintersectimplementation is more performant, but the size ofcapabilitiesandallowedCapabilitiesis typically < 1000, so its not that important.This is a backwards compatible, internal change.
Testing Strategy
New unit tests are introduced.
