Updater: "row index is bigger than sorter's row count"

Every time I launch the updater in either Fiji or ImageJ (under macOS X with the Java 10.0.1 JDK) I get the following error in the Console:
WARNING: row index is bigger than sorter's row count. Most likely this is a wrong sorter usage.

It doesn't seem to have much of an impact on the updater though.

Start by reproducing the updater launch in Fiji or ImageJ on macOS with Java 10.0.1 and capture the full warning context, then trace the updater's table sorting code to identify the source of the row-count mismatch. Done means the updater launches without this warning and its existing behavior remains unchanged.
