I was suprised to see the stack trace below as the top #3 memory allocator in the JFR from CONTROLLER-1864 showing up as 1 GB Total Allocation of String, that's a hell of a lot of objects for what org.opendaylight.ovsdb.lib.notation.Version.fromString() does!
thapar or skitt or any other OVSDB maintainers, how about rewriting that simpler and without allocation?
