This commit modernizes the DB2 client test infrastructure by:

  • upgrading to the community image icr.io/db2_community/db2:12.1.4.0
  • eliminating the JDBC driver dependency
  • removing z/OS testing support (not possible in containerized environments)

Also, a lot of NPE were logged because the DB2SocketConnection#closeHandler was always invoked even if not set.

With all these changes, on my box, the DB2 client build passes in 3-4 minutes instead of 7-8 minutes.

Some portions of this content were created with the assistance of IBM Bob.
