Quartz logging some errors during shutdown

[iscu2020]

Hello,
My Quarkus app (v3.20) uses Quartz, which is configured as follows:

  quarkus:     
    quartz:
      clustered: true
      store-type: jdbc-cmt
      shutdown-wait-time: PT30S
      cron-trigger:
        misfire-policy: cron-trigger-do-nothing
      plugins:
        shutdown:
          class: org.quartz.plugins.management.ShutdownHookPlugin
    shutdown:
      timeout: PT35S

The exception that I see during shutdown is the following:

java.sql.SQLRecoverableException: ORA-17008: Closed connection

It seems that quartz is shut down after the db connections are closed.

How could I make it shutdown properly ?
Thank you !
