Grails 3 : GenericJDBCException: could not prepare statement

Question

Some read queries fail one in ten times with the following message:

org.hibernate.exception.GenericJDBCException: could not prepare statement

The endpoint itself just calls Myclass.findById(myInstanceId), so it is a plugin/library/framework issue.

Having read here that it could be due to conflicting dependencies with hibernate, here are my dependencies:

dependencies {

NB: I found this question, similar to my problem. Setting the testOnBorrow setting to false seems to resolve the issue.
