  * PROBLEM DESCRIPTION: z/OS Connect reports a                  *
  *                      sun.reflect.Reflection.getCallerClass   *
  *                      warning with Java 11 and later.         *
  ****************************************************************
  When the z/OS Connect file system logger interceptor is used
  with Java 11 or Java 17 one of the embedded packages attempted
  to use Multi-Release jar functionality, which was not also
  packaged. This caused the reported warning message to be
  written.
  

Problem conclusion

Temporary fix

Comments

• The z/OS Connect packaging has been changed to include the
  required classes. This allows the file system logger interceptor
  to use the supported classes and prevents the reported warning
  message being written.
  
  
  The fix for this APAR is expected to be delivered by the PTF for
  z/OS Connect EE V3.0.87.0 (PH63792).
