LivenessDebug: Ensuring references dropped on garbage-collected static tables

[nbauernfeind]

The provided query below is quite verbose about dropping references to these intermediate static objects.

import java.util.HashMap
m = new HashMap<String, Object>()
for (int i = 0; i < 10000; ++i) {
    m.put("h_"+i, TableTools.emptyTable(i).view("I=i"))
}

This is particularly confusing during start up of an application that generates only static data. Ideally, we only complain about garbage collection of references to refreshing objects. In the case of refreshing tables, the intermediate parent would be retained.
