Hello, I encountered a bug when implementing composite key with generated value. My code is based on this tutorial: https://vladmihalcea.com/how-to-map-a-composite-identifier-using-an-automatically-generatedvalue-with-jpa-and-hibernate/ .
I did everything like in the link but it does not work with hibernate reactive. When i try to persist my entity i receive weird error:
org.hibernate.HibernateException: java.util.concurrent.CompletionException: org.hibernate.exception.GenericJDBCException: Unable to acquire JDBC Connection [Not using JDBC] [n/a]
When I used the same code in non-reactive hibernate everything is working as intended.
I created 2 reproducers here: https://github.com/majchrzw/composite-key .
main branch show the issue with hibernate reactive, while hibernate-orm branch show the working example.
Can this be somehow fixed?
