Amrit Sarkar updated SOLR-12063:
--------------------------------
Description:
In *UpdateLog*, {{RecentUpdates}} reads the entry of tlogs, and throughout the
project the entry indexes for various operations are consistent, but odd in
this part. As we included new entry in TransactionLog for CDCR, read operations
in {{update()}} method of {{RecentUpdates}} throw error rightfully as elements
are read from wrong indexes of tlog entry. The entry indexes of llog should be
consistent throughout.
