"Server versions prior to 8.0 do not support savepoints" when using JDBC ...

Hello.

I wonder if anyone can assist with this?

Some of my developers are reporting that they are getting the following 
message when attempting to connect to the database using jdbc:

Caused by: org.postgresql.util.PSQLException: Server versions prior to 
8.0 do not support savepoints

at

org.postgresql.jdbc3.AbstractJdbc3Connection.setSavepoint(AbstractJdbc3Connection.java:95)

Database version is 10.5 running under RHEL 7.4. The postgreSQL jdbc 
driver version they're employing is postgresl-42.2.9.

The database itself has absolutely no issues creating savepoints (I 
checked it, just in case ...) so I'm assuming it must be some issue with 
the driver / how the driver has been configured.

As you can see I've not been given a a lot to go on, unfortunately. Has 
anyone seen this before? Is this a common issue and my google-fu has 
failed me? :)

Many thanks.

Regards,

M.
