      • Add debezium.source.database.allowPublicKeyRetrieval=true to the config file in /debezium/conf/application.properties

      We encountered a problem when upgrading Debezium Server from 1.5.3 to 1.6.0 using MySQL connector.

      We use debezium-server in an OpenShift cloud, putting the debezium configuration in /debezium/conf/application.properties
      When using the property debezium.source.database.allowPublicKeyRetrieval=true, the property gets cast to lowercase, as seen in the startup log as the following line:

      2021-08-03 09:20:08,249 INFO  [io.deb.con.com.BaseSourceTask] (pool-3-thread-1)    database.allowpublickeyretrieval = true

      As this property for the MySQL connection is case sensitive (and for us mandatory), debezium cannot establish a connection to our database, producing the following error:
