Unable to run Apache OAK with mySQL as backing store.

I am running a Grails 3.3.5 application with Apache OAK 1.9.8. When I use mySQL(v 5.7) as the backing node store, the application fails to boot-up.

I used org.apache.jackrabbit.oak.plugins.document.rdb.RDBDocumentNodeStoreBuilder to create the repository object. 

At that moment, I get the following exception,

java.sql.SQLException: Connection is read-only. Queries leading to data modification are not allowed. 

This is issue comes even when I have specifically checked that the connection is in write mode and even explicitly opened the connection in write mode.
