Hello, Tomasz Janiszewski kindly started the initiative on the migration to `nullptr`, and we have closed MESOS-3243 <https://issues.apache.org/jira/browse/MESOS-3243>.
The existing instances of `NULL` have been replaced with `nullptr`, and any new or remaining instances of `NULL` are bugs. Please let me know if we missed any, or if there are any that happen to sneak through during this transition period. Thanks, MPark
