[JDBC] Problem updating driver to 42.0.0

Hello,

We are encountering an error when trying to update the driver from
postgresql-9.4.1212 to postgresql-42.0.0 in WebSphere 8.5.5

With 42.0.0, we get:

Failed to create a ConnectionPoolDataSource from PostgreSQL JDBC Driver
42.0.0 for testDB at jdbc:postgresql://localhost:5432/testDB:
java.sql.SQLException: No suitable driver found for
jdbc:postgresql://localhost:5432/testDB

DSRA8201W: DataSource Configuration: DSRA8040I: Failed to connect to the
DataSource DS2.  Encountered java.sql.SQLException: No suitable driver
found for jdbc:postgresql://localhost:5432/testDB DSRA0010E: SQL State =

The driver is in a c:\driver directory. It works if the driver is moved
in AppServer\java_1.8_64\jre\lib\ext, but this is not recommended by IBM.

9.2.1212 and 1211 all work when placed in the same directory.

Thank you,

Bogdan
