  * PROBLEM DESCRIPTION: UnsatisfiedLinkError ERRORCODE=-4472,   *
  *                      SQLSTATE=null: Failure in loading       *

  *                      using Java 17 with CICS Liberty JVM     *
  *                      server.                                 *
  ****************************************************************
  CICS TS JDBC feature (cicsts:jdbc-1.0) can no longer update the
  java.library.path at Liberty startup when using Java 17 - hence
  load of the JDBC native code fails. This is a restriction of the
  Java 17 reference specification.
  

Problem conclusion

• CICS code is updated to update LIBPATH before starting the JVM
  if com.ibm.cics.jvmserver.wlp.jdbc.driver.location and
  autoconfigure=true is set in the JVM profile.
  

Temporary fix
