System.out.println not functioning

Question

What are some scenarios in which java\'s System.out.println would fail to produce any output. I have a call to it inside of a method and sometimes when the method is called

Answer 1

answer as per @BalusC's suggestion--

Thank you for the debugging help. It turned out a blocking call to open a dialog made output appear vastly out of the proper order. I thought the method I was trying to print messages for was being called when the dialog closed but the method itself was what was calling the dialog and so after the closing it was already passed the printouts which were where I started looking for the test. If someone has the ability to delete this question as the issue was not what was originally asked it'd be appreciated.
