Chetan Mehrotra commented on OAK-5309:
--------------------------------------
Looks fine.
To confirm my understanding here startRevisionGC() -> Filter map [role:null]
-> Select RevisionGCMBean where role property is not present. So in a filter if
a key value is null then that would result in a filter which would ensure that
a service candidate does not have that property defined.

> With recent support for maintenance task MBeans exposed for secondary stores
> via OAK-4978 its now possible to have multiple implementations of
> RevisionGCMBean present in same setup.
> However o.a.j.o.management.RepositoryManager implementation only supports
> single implementation by design. This needs to be updated to support
> # Looking up RevisionGCMBean which does not have {{role}} OSGi property
> defined
> # Expose a management op like startRevisionGCForRole
