Stalling connection after running some command

This occurs only with version 22.08.2 (tested with 6.4.3 without issue)
I have not exactly point the problem, but i can reproduced it every time.

To reproduce : run a test case from r2dbc connector (have java and maven installed)

git clone https://github.com/mariadb-corporation/mariadb-connector-r2dbc

cd mariadb-connector-r2dbc

git checkout develop

change values of src/test/conf.properties to maxscale server

then run

mvn test -Dtest=StatementTest#metadataNotSkipped

the test never ends.
directly using server or maxscale 6.4.3 works ok
