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.
