PM40776: THE WMQFTE ANT EMAIL FUNCTION HANGS ON Z/OS

WebSphere MQ File Transfer Edition V7.0 Fix Pack 7.0.4.1

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.
