Description

The lucene index produced by TreeMergeRecordWriter when the segments are merged doesn't contain Solr's commit data, specifically, commitTimeMsec.

This means that when this index is subsequently loaded into SolrCloud and if the index stays unchanged so no newer commits occurs, ADDREPLICA will appear to succeed but will not actually do any full sync due to SOLR-9369, resulting in adding an empty index as a replica.
