After upgrading to Rundeck 5.20.0 release; we see the following errors repeatedly in service.log:

[2026-06-09T15:59:50,795] ERROR spi.SqlExceptionHelper - Unsupported conversion from DECIMAL to java.sql.Time
[2026-06-09T15:59:50,975] WARN  spi.SqlExceptionHelper - SQL Error: 0, SQLState: 22018
[2026-06-09T15:59:50,975] WARN  spi.SqlExceptionHelper - SQL Error: 0, SQLState: 22018

 

This is Rundeck 5.20.0 running on Oracle Linux 9.  The database being used is 8.0.46-commercial and Rundeck is connectiving via mysql-connector-j-9.7.0.jar .  Any suggestions?
