Jet 4.5 map source updating "other" operations count, not "get" count

[neilstevenson]

Using Jet 4.5, and map source, some report as "GET" operations and some as "OTHER"

https://github.com/hazelcast/hazelcast-platform-demos/blob/master/banking/credit-value-adjustment/jet-jobs/src/main/java/com/hazelcast/platform/demos/banking/cva/cvastp/CvaStpJob.java#L344
gives
"cva_ircurves"

but
https://github.com/hazelcast/hazelcast-platform-demos/blob/master/banking/credit-value-adjustment/jet-jobs/src/main/java/com/hazelcast/platform/demos/banking/cva/cvastp/CvaStpJob.java#L340
gives
"cva_trades"

Cross checked with Prometheus:

hz_map_getCount increases only for one map, cva_trades, although this could be due to something else.

Other maps used by the job, including cva_trades show an increasing value for hz_map_numberOfOtherOperations

It's partly this, https://github.com/hazelcast/hazelcast/blob/master/hazelcast/src/main/java/com/hazelcast/jet/impl/connector/ReadMapOrCacheP.java but unclear why cva_trades has a get count.
