Description
Process Instance Migration service cannot start with Oracle 19c. This has been observed in nightlies after RHPAM-3030 has been fixed, so I expect the same issue in the CR2 build. During the startup, this stackTrace is displayed:

The most important part is:
Unable to determine Dialect to use [name=Oracle, majorVersion=19]; user must register resolver or explicitly set 'hibernate.dialect'
It looks like we are hitting a Hibernate bug
HHH-13184 so in case a newer DB than 12c is used, Hibernate cannot automatically resolve the dialect properly as the latest one is Oracle12cDialect. Moreover with PIM service we depend on automatic detection of a JDBC driver and dialect, so we cannot set it manually.
We also cannot upgrade Thorntail as we use the latest version already (2.7.0.Thorntail), so Thorntail should upgrade to at least Hibernate 5.3.16.Final. But even on master, they are still aligned with Wildfly 18.0.1.Final which has only 5.3.15.Final. Even the wildfly-parent which we are aligned to (19.1.0.Final) has only 5.3.15.Final. Only 20.0.0.Final has 5.3.17.Final, which contains the fix.
