We had been using kamon and iam-jdbc for postgresql without problems, but as iam-jdbc uses AWS-SDK v.1, we would like to migrate to the AWS advanced JDBC wrapper. Initializing the HikariPool fails with the following exception:

java.lang.ClassCastException: class software.amazon.jdbc.wrapper.ConnectionWrapper cannot be cast to class kamon.instrumentation.jdbc.HasConnectionPoolTelemetry (software.amazon.jdbc.wrapper.ConnectionWrapper and kamon.instrumentation.jdbc.HasConnectionPoolTelemetry are in unnamed module of loader 'app')
at kamon.instrumentation.jdbc.PoolBaseNewConnectionAdvice$.enter(HikariInstrumentation.scala:221)
at com.zaxxer.hikari.pool.PoolBase.setupConnection(PoolBase.java:406)
at com.zaxxer.hikari.pool.PoolBase.newConnection(PoolBase.java:374)
at com.zaxxer.hikari.pool.PoolBase.newPoolEntry(PoolBase.java:198)

at com.zaxxer.hikari.pool.HikariPool.(HikariPool.java:115)
at com.zaxxer.hikari.HikariDataSource.getConnection(HikariDataSource.java:112)

The only enabled AWS wrapper plugin is "iam".
Versions:

"org.postgresql"        % "postgresql"                % "42.6.1"
"software.amazon.jdbc"  % "aws-advanced-jdbc-wrapper" % "2.5.3"
"org.tpolecat"         %% "doobie-hikari"             % "1.0.0-RC2"
"org.scalikejdbc"      %% "scalikejdbc"               % "4.2.3"  #updated
"io.kamon"             %% "kamon-bundle"              % "2.7.3"
"io.kamon"              % "kanela-agent"              % "1.0.18"

Does anybody know how to make Kamon work with the Advanced AWS JDBC wrapper?

Thanks a lot!
