 In case the responsible employee is unreachable for a longer period or issues with the dialect are not attended to in a timely manner,
 the Hibernate team will move the dialect back to the `hibernate-community-dialects` artifact.
 
+The requirements for the database server are:

+* JDK 8 installed through e.g. `sudo yum install -y java-1.8.0-openjdk-devel`
+* JDK 11 installed through e.g. `sudo yum install -y java-11-openjdk-devel`

 if you want to request the move of your dialect to hibernate-core.
