Dave Marion commented on ACCUMULO-4329:
---------------------------------------

No, the port search works when enabled. I get the following in the monitor log:

```

>    Affects Versions: 1.8.0

> TabletServer will not start if it cannot reserve the configured replication port. The
code passes `null` for enabling the port search feature, which resolves to `false`, and the
TServer fails.
