IJ41549: COMMAND-LINE ARGUMENT FILES DO NOT WORK ON Z/OS

APAR status

• Closed as program error.

Error description

• Error Message: Could not find or load main class @filename
  aused by: java.lang.ClassNotFoundException: @filename
  .
  Stack Trace:
  .
  The entire word "@filename" is being wrongly treated as a main
  class name, either leading to or causing a failure.
  

Local fix

• There is no clear workaround to get the command-line argument
  file without any code change, other than to pass in the
  arguments normally without going through a file.
  

Problem summary

• Command line argument files are not handled properly on z/OS.
  Due to incorrect handling of EBCDIC encoding, the '@' is not
  recognized and the file name is treated like a main class name.
  Furthermore, the file contents cannot be parsed properly on z/OS
  due to encoding inconsistencies of handling ASCII files in a
  z/OS java environment.
  

Problem conclusion

• Command line argument file declaration is now recognized by
  detecting the '@' indicator. Support has been added for
  recognition of ISO-8859-1 command-line argument files.
