Problem summary

• ****************************************************************
  * USERS AFFECTED:  IBM WebSphere Application Server version    *
  *                  8.5 Liberty Profile users.                  *
  ****************************************************************
  * PROBLEM DESCRIPTION: DBCS response data is missing.          *

  * RECOMMENDATION:                                              *
  ****************************************************************
  When the application generates DBCS data and closes the
  response explicitly, the client might not be able to receive
  some data.
  The WebContainer tries to set the content-length header when
  the response.close() is called explicitly by the application.
  When any of the response's data characters is made up by three
  or more bytes, the content-length will not be calculated
  correctly at closing time.  The response data length might
  change when the data is encoded, causing the response data to
  be larger than the previously calculated content-length. This
  causes the client to read the response data up to the size of
  the content-length and ignore the rest of the data, making it
  appear as if there is missing data
  It is not a problem when the application does not close the
  response explicitly.
  

Problem conclusion

• The WebContainer code was modified to not set the
  content-length if the application closes the response by
  itself.
  
  A new WebContainer customer property needs to be set to enable
  the behavior provided by this APAR:
  
  setContentLengthOnClose = false (default is true)

  enabling WebContainer custom properties:

  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.0.2. Please refer to the Recommended Updates page
