  The gtk version is gtk2 2.24.25-1 as shown by the command:
  rpm -qa --last | grep gtk output
  
  The eclipse FAQ say that this Problem occurs only with 2.10 to
  2.12. We observe this problem also in Eclipse version 4.2.2
  
  Eclipse Bugzilla Bug  130676
  https://bugs.ottawa.ibm.com/show_bug.cgi?id=130676
  

Local fix

• In the RDz install directory add the flag
  "-Dorg.eclipse.swt.internal.gtk.disablePrinting" to the end of
  the "\eclipse.ini" file.
  Then restart RDz
  

Problem summary

• See error description.
  

Problem conclusion

• In order to circumvent the errant behaviour in Eclipse, LPEX no
  longer attempts to enumerate print devices before determining
  wether or not to enable the print button. The print button is
  now always enabled.
  
  The problem listed in this APAR has been resolved with
  IBM Rational Developer for System z V9.0.1.5 Fix Pack which
  is available from the Recommended Fixes support download page:
