APAR status

  • Closed as program error.

Error description

  • The Ant e-mail function with WMQFTE on z/OS does not work.  The
    SMTP server is contacted but the send of the e-mail does not
    occur because of a hang following the first contact.  Eventually
    the SMTP server times out the connection.
    

Local fix

Problem summary

  • The hang is a result of two problems with Ant:
    
    1) Writing newline characters to an output stream does not cause
    the stream to flush on z/OS.
    
    2) The incorrect codepage is used to create MIME headers.
    EBCDIC is used instead of UTF-8.
    
    As a result, communication with the SMTP server hangs.
    

Problem conclusion

  • This APAR resolves the problem by supplying a patched version of
    Ant with WMQFTE that fixes the two issues:
    
    1) The fix for this is to look at the end of any string being
    written. If it ends /n or /r/n, PrintStream.flush() is invoked
    manually.
    
    2) Ensure that UTF-8 is used to encode String data when creating
    MIME headers.
    
    Apache Jira bug 51353 has been raised for this issue.
