Kathey Marsden commented on DERBY-5582:
---------------------------------------


I have to say eclipse is pretty infuriating in this regard.  I try to switch it back and forth based on where I am but it insists on odd things.  I will fix the tab in AutomaticIndexStatisticsTest and leave SecurityManagerSetup reformating for now.   Looking at history of this  file I see Kristian seems to take the approach of always using spaces for new lines, even when the surrounding code is tabs. Maybe that is the best way to go.
